On the monthly time scale, July had the worst rainfall in the recorded history of monsoon dating back to middle of nineteenth century when the country as a whole registered rainfall deficiency of 51.5%. Another notable feature was that for the first time in the last 133 years, not a single depression or cyclonic storm formed during the whole southwest monsoon season. The advance of monsoon over India was accompanied with frequent as well as prolonged stagnations. The monsoon failed to arrive for the first time in extreme northwest India during the first half of the season since 1960. In the present study, various features of monsoon such as onset, progress, stagnation, different synoptic and semi-permanent features and characteristics of rainfall of southwest monsoon in 2002 over India have been discussed. A comparison of these features with those in the earlier drought years has been made. Large-scale mean monthly anomalous ocean and atmospheric conditions over Indo-Pacific region have also been investigated to find out the possible causes for drastic failure of the monsoon during July 2002. Results show that many abnormal and unique features during 2002 have resulted into all India drought. Study also shows that absence of favourable regional intra-seasonal features like monsoon disturbances and semi-permanent systems, presence of very weak low level jet, penetration of strong mid-latitude westerlies, weak to moderate El-Nino with most intense warming over Nino 4 region of Pacific Ocean during monsoon months together with higher frequency of typhoon formation over the region are the main causes that led to one of the highly pronounced rainfall deficiencies in the month of July.

The characteristic features of I. Kavaleridze’s drama is considered in the article. It is noted that there are signs of the artist’s individuality, attraction to expressionist forms, artistic techniques characteristic for the art of sculpture: symbolism, monumentality, hyperbole. I. Kavaleridze was well versed in the drama laws, understood the specifics of the stage events construction, had a large arsenal of literary means, thanks to which the characters’ monologues and dialogues were extremely expressive and colorful. In his work, he implemented original solutions that were ahead of time. Therefore, many of the artist’s ideas and achievements received due recognition only after his death. I. Kavaleridze’s creative heritage covers a wide range of both purely artistic and general philosophical problems. Among them the formation of the era of modernism and its features in the Ukrainian art of the early XX century, the impact of revolutionary ideas on the work of the 1920s, the role of spiritual leaders of the Ukrainian people T. Shevchenko and G. Skovoroda in the formation of national consciousness, political and ideological pressure on figurative art language and the formation of a socialist-realist canon, etc. The analysis of the productions of I. Kavalerizde’s plays “The First Furrow” and “Gregory and Paraskeva” on the stage of the Mykhailo Shchepkin Sumy Theater of Drama and Musical Comedy in 1970-1972. The article notes that these plays were staged in Sumy for the first time in the history of Ukrainian theater. The premiere of “The First Furrow” (the play was called “Old Men”) took place on March 19, 1970. The figure of the national genius Hryhoriy Skov oroda was als o embodied for the first time on t he stage in Sumy in th e play “Hryhoriy and Paraskeva”. It premiered on October 21, 1972. I. Rybchynsky, Honored Artist of the USSR, performed the production. Creating generalized historical outlines of people’s life, features of life at that time, depicting psychological portraits of people in various, sometimes-dramatic collisions, in the productions of I. Kavaleridze’s plays on the Sumy stage the emphasis was on universal values such as virtue, love. The main character was the Ukrainian people, who nurtured such large-scale historical figures, gave them strength and wisdom for great achievements. Based on publications in periodicals of that time, memoirs of Ukrainian directors, the peculiarities of the director’s interpretation, stenographic and musical design of these plays on the Sumy stage are considered. Considerable attention is paid to the analysis of acting works in I. Kavaleridze’s plays. In particular, the peculiarities of the actor’s embodiment of the image of the national genius Hryhoriy Skovoroda on the stage are presented. It is noted that I. Kavaleridze’s plays, created in a difficult political, social and ideological context, are rightly considered to be highly artistic works of Ukrainian drama. Their staging was carried out on various theatrical stages, including Mykhailo Shchepkin Sumy Theater of Drama and Musical Comedy is an important page of national theatrical art.

Abstract In 2013, the Department of Archaeology, School of History of Wuhan University and the Panlongcheng City Ruins Museum excavated seven burials of the Shang Dynasty at Yangjiawan Locality within the Panlongcheng Site in Wuhan City. All the burials were vertical earthen shaft burials. Some of the burials featured waist pits, human and/or animal sacrifices. The grave goods assemblage included artifacts made of bronze, jade, stone, pottery, gold and turquoise. Some of the unearthed objects were seen for the first time in the archaeology of Panlongcheng. The burials can be roughly dated to the terminal phase of the Panlongcheng Site. The Yangjiawan Locality yielded the densest distribution of burials in the Panlongcheng Site. It was an important cemetery of the early to the mid Shang Dynasty. The cemetery was in close proximity to a previously excavated large-scale architectural foundation of the Shang Dynasty. Together, these findings are important information for the understanding of the layout of the Panlongcheng Site.

It seems inherent in the nature of contemporary artist’s book production to continue to question the context for the genre in contemporary art practice, notwithstanding the medium’s potential for dissemination via mass production and an unquestionable advantage of portability for distribution. Artists, curators and editors operating in this sector look to create contexts for books in a variety of imaginative ways, through exhibition, commission, installations, performance and, of course as documentation. Broadening the discussion of the idea of the book within contemporary art practice, this paper examines the presence and role of book works within the context of the art biennale, in particular the Venice Art Biennale of which the 58th iteration (2019) is entitled ‘May You Live In Interesting Times’ and curated by Ralph Rugoff, with an overview of the independent International cultural offerings and the function of the ‘Book Pavilion’. Venetian museums and institutions continue to present vibrant diverse works within the arena of large-scale exhibitions, recognising the position that the book occupies in the history of the city. This year, the appearance for the first time, of ‘Book Biennale’, opens up a new and interesting dialogue, taking the measure of how the book is being promoted and its particular function for visual communication within the arts in Venice and beyond.

Abstract. Water risk management is a ubiquitous challenge faced by stakeholders in the water or agricultural sector. We present a methodological framework for forecasting water storage requirements and present an application of this methodology to risk assessment in India. The application focused on forecasting crop water stress for potatoes grown during the monsoon season in the Satara district of Maharashtra. Pre-season large-scale climate predictors used to forecast water stress were selected based on an exhaustive search method that evaluates for highest ranked probability skill score and lowest root-mean-squared error in a leave-one-out cross-validation mode. Adaptive forecasts were made in the years 2001 to 2013 using the identified predictors and a non-parametric k-nearest neighbors approach. The accuracy of the adaptive forecasts (2001–2013) was judged based on directional concordance and contingency metrics such as hit/miss rate and false alarms. Based on these criteria, our forecasts were correct 9 out of 13 times, with two misses and two false alarms. The results of these drought forecasts were compared with precipitation forecasts from the Indian Meteorological Department (IMD). We assert that it is necessary to couple informative water stress indices with an effective forecasting methodology to maximize the utility of such indices, thereby optimizing water management decisions.

В статье представлены предварительные результаты первых масштабных археологических исследований в нижней части Нижегородского кремля. Раскоп, заложенный в зоне воссоздания храма Святого Симеона Столпника, вскрыл культурные отложения двух периодов - XIII - начала XV в. и XVI - середины XVIII в. Впервые средневековая усадебная застройка Нижнего Новгорода зафиксирована на таком элементе волжской долины, как береговой склон. Выдающееся значение для нижегородской археологии имеют обнаружение стратифицированных культурных напластований XIII - начала XV в. и зафиксированный на стратиграфических разрезах перерыв в активном освоении городской территории, соответствующий большей части XV в. Предложена реконструкция истории освоения раскопанного участка. Выяснилось, что связанный с храмом малоизвестный нижегородский Симеоновский монастырь вряд ли существовал до строительства Нижегородского кремля. Наиболее раннее, предположительно, монастырское сооружение, возникшее после исчезновения усадебной застройки XIII - начала XV в., датировано концом XV - серединой XVI в. С этим периодом связано строительство деревянного моста, обеспечивавшего транспортное сообщение между «нагорным» и приречным районами города. Обнаружение остатков этого свайного сооружения существенно корректирует известную реконструкцию застройки кремлевской территории начала XVII в., выполненную по письменным источникам. Дано обоснование времени функционирования обнаруженного некрополя Симеоновского монастыря в пределах середины XVI - начала XVIII в., приведена общая характеристика изученных погребений. В общеисторическом контексте материалы исследований представляют интерес для изучения процессов, сопровождающих превращение удельных городских центров в города Московской Руси. The article presents preliminary results of the first large-scale archaeological research in the lower part of the Nizhniy Novgorod Kremlin. The excavation, laid in the area of the reconstruction of the Church of St. Simeon the Stylite, uncovered cultural layer of two periods - the XIII - early XV centuries and the XVI - mid XVIII centuries. For the first time, the medieval estate development of Nizhniy Novgorod was recorded on such an element of the Volga valley as the coastal slope. The discovery of stratified cultural strata of the XIII - early XV centuries and the break in the active development of urban territory recorded on stratigraphic sections, corresponding to most of the XV century, are of outstanding significance for Nizhniy Novgorod archeology. The reconstruction of the history of development of the excavated site is proposed. It turned out that the little-known Nizhniy Novgorod Simeon monastery associated with the temple hardly existed before the construction of the Nizhniy Novgorod Kremlin. The earliest, presumably, monastic structure that arose after the disappearance of the manor buildings of the XIII -early XV centuries., dated to the end of the XV - mid XVI centuries. This period is associated with the construction of a wooden bridge that provided transport links between the «Nagorny» and riverine districts of the city. The discovery of the remains of this pile structure significantly corrects the well-known reconstruction of the Kremlin territory of the beginning of the XVII century, made according to written sources. The justification for the functioning of the necropolis discovered Simeon monastery in the middle of the XVI century - beginning of the XVIII centuries, the general characteristics of the studied burials. In the general historical context, the research materials are of interest for studying the processes that accompany the transformation of specific urban centers into cities of Muscovite Russia.

Abstract. South Asia is strongly influenced by the so-called Atmospheric Brown Cloud (ABC), a wide polluted layer extending from the Indian Ocean to the Himalayas during the winter and pre-monsoon seasons (November to April). This thick, grey-brown haze blanket substantially interacts with the incoming solar radiation, causing a cooling of the Earth's surface and a warming of the atmosphere, thus influencing the monsoon system and climate. In this area, the Himalayan region, particularly sensitive to climate change, offers a unique opportunity to detect global change processes and to analyse the influence of anthropogenic pollution on background atmospheric conditions through continuous monitoring activities. This paper provides a detailed description of the atmospheric conditions characterizing the high Himalayas, thanks to continuous observations begun in March 2006 at the Nepal Climate Observatory – Pyramid (NCO-P) located at 5079 m a.s.l. on the southern foothills of Mt. Everest, in the framework of ABC-UNEP and SHARE-Ev-K2-CNR projects. Besides giving an overview of the measurement site and experimental activities, the work presents an in-depth characterization of meteorological conditions and air-mass circulation at NCO-P during the first two years of activity (March 2006–February 2008). The mean values of atmospheric pressure, temperature and wind speed recorded at the site were: 551 hPa, −3.0 °C, 4.7 m s−1, respectively. The highest seasonal values of temperature (1.7 °C) and relative humidity (94%) were registered during the monsoon season, which was also characterized by thick clouds present in about 80% of the afternoon hours and by a frequency of cloud-free sky less than 10%. The lowest temperature and relative humidity values were registered during winter, −6.3 °C and 22%, respectively, the season being characterised by mainly cloud-free sky conditions and rare thick clouds. The summer monsoon influenced the rain precipitation (seasonal mean 237 mm), while wind was dominated by flows from the bottom of the valley (S-SW) and upper mountain (N-NE). In relation to seasonal weather conditions, the time series variability of black carbon and dust particles (optical active aerosols) and ozone (regional greenhouse gas) were analysed, as they are significant constituents of the Atmospheric Brown Cloud and strongly influence the atmospheric radiative forcing. The highest seasonal values of black carbon (BC), ozone (O3) and dust particles were observed during the pre-monsoon season (316.9 ng m−3, 60.9 ppbv, 0.37 cm−3, respectively), while the lowest concentrations occurred during the monsoon for BC and O3 (49.6 ng m−3 and 33.6 ppbv, respectively) and post-monsoon for dust particles (0.07 cm−3). The seasonal cycles of these compounds are influenced both by the local mountain wind system and by the three principal large-scale circulation regimes: Westerly, South-Westerly and Regional, as shown by the analysis of in-situ meteorological parameters and 5-day LAGRANTO back-trajectories. In particular, the analysis of data representative of synoptic-scale circulation showed that the highest median values (O3: 68 ppbv, BC: 124 ng m−3, dust particles: 0.44 cm−3, respectively) were related with air-masses from polluted and arid regions in the Indian subcontinent, as well as the Arabian Peninsula and Persian Gulf. Furthermore, it was documented that in 90% of pre-monsoon days the Khumbu valley represents a "direct channel" able to transport polluted air-masses from the Asian Brown Cloud up to NCO-P and to higher altitudes. On such days the average day-time BC concentration (625 ng m−3) was at least double that recorded on the remaining days, even if during some pollution hot spots BC daily values increased up to 1000 ng m−3. In this study, two years of Himalayan observation activities carried out at NCO-P, in conjunction with model circulation analyses, provide some of the first evidence that polluted air-masses linked to the Atmospheric Brown Cloud can reach the high Himalayas, in particular during the pre-monsoon season, influencing the pristine atmospheric composition.

Abstract The performance of operational extended range forecast (ERF) issued by IMD is evaluated for the southwest monsoon 2020. The early onset of monsoon over the Bay of Bengal and the normal onset of monsoon over Kerala with slightly rapid progress northward are very well captured in the ERF with two to three weeks lead time. The ERF also captured very well the transitions from normal to weaker phase of monsoon in July, the active phase of monsoon in entire August was well anticipated in ERF with a lead time of 3 weeks. The active monsoon condition in the second half of September associated with delayed withdrawal from northwest India was also reasonably well captured in the ERF. Quantitatively, the ERF shows significant skill up to three weeks on all India levels. The spatial distribution of met-subdivision level mean forecast skill of predicting above normal, normal and below normal categories in terms of correct (forecast and observed category matching) and partially correct (forecast and observed category out by one category) for the 36 subdivisions during the entire monsoon season of 2020 is found to be 89%, 83%, 80% and 78% for week 1 to week 4 forecasts respectively. The wrong forecasts (forecast and observed category out by two categories) are found to be between 11% in week 1 to 22% in week 4 forecast. Thus, the met-subdivision level forecast shows useful skill and is being used operationally for agrometeorological advisory services of IMD.

Abstract. The AMMA (African Monsoon Multidisciplinary Analysis) program is dedicated to providing a better understanding of the West African monsoon and its influence on the physical, chemical and biological environment regionally and globally, as well as relating variability of this monsoon system to issues of health, water resources, food security and demography for West African nations. Within this framework, an intensive field campaign took place during the summer of 2006 to better document specific processes and weather systems at various key stages of this monsoon season. This campaign was embedded within a longer observation period that documented the annual cycle of surface and atmospheric conditions between 2005 and 2007. The present paper provides a large and regional scale overview of the 2006 summer monsoon season, that includes consideration of of the convective activity, mean atmospheric circulation and synoptic/intraseasonal weather systems, oceanic and land surface conditions, continental hydrology, dust concentration and ozone distribution. The 2006 African summer monsoon was a near-normal rainy season except for a large-scale rainfall excess north of 15° N. This monsoon season was also characterized by a 10-day delayed onset compared to climatology, with convection becoming developed only after 10 July. This onset delay impacted the continental hydrology, soil moisture and vegetation dynamics as well as dust emission. More details of some less-well-known atmospheric features in the African monsoon at intraseasonal and synoptic scales are provided in order to promote future research in these areas.

The article assesses source and archival studies aspects of the V. P. Kozlov’s book “Remove to history ...”: The Peasant Family and Settlement of the Tula Region in the 16th – 20th Centuries. It is the first volume of the study, covering the period up to 1917. The work is devoted to the history and culture of the Yepifan uezd. This uezd is considered in two ways: as a territory, including the villages where the author’s ancestors lived, and as a part of its surroundings. The state of the territory is described for several periods. Via stepwise immersion accompanied by detailing of material, the author advances the restoration of the history of villages and their inhabitants. In the Russian scientific literature, an experience of large-scale and consistent implementation of this approach is a unique case. The author analyzes it theoretically, bringing it into correlation with trends of modern historical science and demonstrating its effectiveness. To study the history of the Yepifan uezd, a significant amount of documents, both published and stored in the archives, has been involved for the first time. V.P. Kozlov divides sources into three classes. In line with his approach used in his works on archeography, he characterizes eight types of sources. Among sources of personal provenance, he underscores oral history documents — records of his relatives’ memoirs collected over the years. He points to the cognitive heterogeneity of these sources: he emphasizes the need to take into account the “author's angles,” notes high reliability of correspondence, especially between relatives. Isolation by V. P. Kozlov of a special class of sacred documentary sources is new. The author refers to these documents as reflecting “relations with the sacred ... beliefs, convictions and symbols” and capturing “the sacrament of human communication with... extrahuman authority.” As an example, he cites his grandmother’s nightly prayers and recordings of miracles of St. Matrona of Moscow. V. P. Kozlov notes an abundance of such sources in the Russian archives. Identifying gaps in sources, he explains the reasons for different preservation of documentary complexes. He dwells on research methods that can partially compensate for the insufficiency of sources. He took some risk in choosing the inhabitants of a small village as main characters of his research. The analysis of source study and archival aspects of his research proves that such work can be successfully carried out even with insufficient sources.
