The present paper is an attempt to educate the weather forecaster at Indian Scientific research Station, Maitri, Antarctica in forecasting severe weather (blizzards) using satellite images of various satellites operating in the world. The Polar stationary satellite ‘Trianna’ has been discussed .The availability of the various types of images has also been spelt. The characteristics of satellite images has been described along with overlaying of Automatic Weather station (AWS) data explaining the occurrence of Katabatic winds which also causes blizzards. Blizzard conditions often develop on the northwest side of an intense storm system the difference between the lower pressure in the storm and the higher pressure to the west creates a tight pressure gradient, which in turn results in very strong winds or blizzards. The paper also discusses about the development that took place in Antarctic satellite meteorology since beginning.

<p>Although social media industry is now a very congested Marketplace, Twitter continues to maintain its status as a popular social media platform. There are 330 million monthly active users and 145 million daily active users on Twitter sending more than 6,000 tweets every second in the world. In Spain case 85% population are social media users, with around 5 million tweeter profiles for a population around 47 million. In the autonomous community of Basque country (2.17 million inhabitants) around 20% of citizens use Twitter.</p><p>Twitter is a social tool that enables users to post messages (tweets) of up to 280 characters supporting a wide variety of social communication practices including photo and video attach. The Basque Meteorology Agency @Euskalmet with more than 115,3 K followers is one of the most popular accounts in Basque Country. Twitter is not only an opportunity to instantaneous spread messages to people without intermediaries, but also as a potential platform for valuable data acquisition using tweeter API capabilities. In this contribution, we present a study of different aspects related to the operational use of Twitter data in the context of high impact weather scenarios at local level.</p><p>The most important activity in Euskalmet are actions in severe weather events. Before the event, mainly centered in forecast and communication, during the event in nowcast, surveillance and impact monitoring and after the event in post-event analysis. During all these complex processes real time tweets posted by local users offer a huge amount of data that conveniently processed could be useful for different purposes. For operational staff, working at office during severe weather episodes, is critical to understand the local effects that an adverse phenomenon is causing and the correct perception of the extent of impact and social alarm. For this purposes, among others, different information associated with posted tweets can be extracted and exploited conveniently. In this work, we present some results that demonstrate how different data mining and advances analytics techniques can be used in order to include social media data information for different tasks and particularly during high impact weather events.</p><p>In this paper we summarize our experience during a proof of concept project for automatic real time tweeter analysis and the development of an operational tool for tweeter API data exploitation in the Basque Country. We present the main challenges and problems that we have had to face, including how to deal with the lack of geolocation information, since in the case of the Basque country, as in other parts of the world, tweets containing geotags are the exception, not the rule.</p>

The article describes a method of mapping climatic parameters (i. e. frequency and intensity) of severe weather events, based on the interpolation of weather station data. We applied regression-based interpolation, using some geographical variables (altitude, slope angle and curvature) for modeling their spatial distribution. Statistically significant correlations between geographical and climatic variables were selected based on regression analysis. They have been used to create a maps of frequency, average and maximum intensity of severe weather events for Perm region (160 600 km2). The proposed method allows to create more accurate and detailed maps of spatial distribution of severe weather events than traditional deterministic and geostatistical interpolation methods. The reliability of the results confirmed by a weather station observations and comparisons with MODIS satellite images thematic products. Significant advantage of proposed method is also its applicability to the risk assessment of severe weather events in ungauged site, or in ungauged areas.

‘Informal colonialism’ and ‘informal imperialism’ are relatively common terms in the specialized literature. The term ‘informal colonialism’ was coined—or at least sanctioned—by C. R. Fay (1940: (vol. 2) 399) meaning a situation in which a powerful nation manages to establish dominant control in a territory over which it does not have sovereignty. The term was popularized by the economic historians John Gallagher and Ronald Robinson (1953), who applied it to study informal British imperial expansion over portions of Africa. The difference between informal and formal colonialism is easy to establish: in the first instance, complete effective control is unfeasible, mainly due to the impossibility of applying direct military and political force in countries that, in fact, are politically independent. They have their own laws, make decisions on when and where to open museums and how to educate their own citizens. Yet, in order to survive in the international world they need to build alliances with the main powers, and that comes at a price. Many countries in the world were in this situation in the middle and last decades of the nineteenth century: Mediterranean Europe, the Ottoman Empire, Persia, and independent states in the Far East and in Central and South America. A simple classification of countries into imperial powers, informal empires and formal colonies is, however, only a helpful analytical tool that shows its flaws at closer look. Some of those that are being included as informal colonies in Part II of this book were empires in themselves, like the Ottoman Empire and, from the last years of the century, Italy (La Rosa 1986), and therefore had their own informal and formal colonies. The reason why they have been placed together here is that in all of them there was an acknowledgement of a need for modernization following Western-dominated models. They all had the (northern) European presence in their lands—at first primarily British and French, followed by Germans and individuals of other European states, mainly from other empires either alive such as that of Austria- Hungary or in decline like Sweden and Denmark.

Sudden weather events seem to fit in the Polish climate for good. Recent meteorological phenomena in the form of storms, tempests and precipitation are the best proofs for this. This is primarily due to the climatic changes that make the weather last, even in other parts of the world. In this article the author characterizes extreme weather phenomena on the territory of Poland in the context of climate change.

Gender distribution in all creatures is a sign of Nature. For human guide it seems to realize the gender division that is found distinctive in physical nature, man and woman with entirely different physique, that all other religions admit the difference but their societal customs have counted on equal gesture. That is the reason modern societies are now viewing no problem at homosexual contact in the west, without ascertaining the results of failures in saving their nation from a purgatory desire in their youth, who have forgotten how to quench their natural thirst from the right way, of having marriage with opposite gender. This study will explain how west has allowed doing homosexuality, contrary to which no religion has allowed freedom against the natural way. Islamic teachings are proactive in restricting these kinds of illegal trails for the safety human folk. Conclusively it is clarified that due to denial of religious teachings, there are arising big issues of gender-wise sins in the world that is also arresting Muslim youth too. Therefore, only the religious theories are advisable to all humankind for safety of human-identity. Thus, Islam teaching can never allow promoting the western’s theories of ‘sexuality’ amongst Muslim community.

The issue of politics and ethics are two sides of a coin that invited attention of medieval scholars both in the West and the Islamic world. Although interrelated, but the implementation raises the difference between the two worlds. For the Western world, represented by Machiavelli, politics and ethics should be separated. A ruler should not be bound by ethics and tradition, and does not need to obey the law. In domestic relations affairs, a ruler must collect on his love and fear of people. While in foreign affairs, a ruler must reflect "a smart wolf and a strong lion. As for the world of Islam represented by al-Mawardi, politics and ethics cannot be separated. Even the basics of government, he said, are inspired by Islamic values based on the Qur'an and Hadith. Even a ruler must have and improve its ethical because it is a basic rule.

1. Extreme Weather and Water-Related Disasters Extreme weather events frequently take place in many parts of the world, causing various kinds of water-related disasters such as windstorms, floods, high tides, debris flows, droughts, and water-quality issues. This is a key issue for the sustainability and survivability of our society. The Asian and Pacific region is one of the most disaster-prone areas in the world. It is very adversely affected by natural hazards such as cyclones and typhoons and tsunami caused by earthquakes and volcanic eruptions under the sea. These natural hazards bring severe disasters to all countries in the region where social change, in terms of population and economic growth, is the most dynamic in the world. Growth in this region of the world has not, however, led to advances in disaster risk management. The situation is getting worse because infrastructure development cannot keep up with growth. Policies for poverty reduction and alleviation are insufficient and the difference between being rich and being poor is increasing. Vulnerable populations are often those hit worst by hazards and disasters. As the world’s cities expand to occupy ever greater portions of the world’s flood plains, riversides and shorelines, the risk of flooding will continue to outpace both structural and nonstructural mitigation efforts. “A natural hazard strikes when persons lose their memory of the previous one.” This quotation is from Dr. Torahiko Terada (1878-1935), a former Professor of the University of Tokyo who influenced many Japanese persons as an educator, physicist and philosopher. Persons tend to forget bad memories if they do not experience a similar event for a long time. This lack of experience and ignorance increases the vulnerability of society to disasters.

Europe is facing numerous challenges, many of which are unprecedented either in their scale or in their nature. These challenges include uncertainties about the future of the liberal international order and the rise of populist movements in the West. And there are also tensions and reform pressures in the areas of international trade, climate change and extreme weather events; pressures linked to migration from the Middle East and North Africa; hybrid threats and cyberattacks; and problems related to the expected departure of the UK from the EU by the end of March 2019. During its forthcoming Council Presidency in autumn 2019, Finland will have the opportunity to propose new solutions to these and other challenges. This article argues that it is important for Europe’s leaders to clearly articulate and put into words what the EU’s positions and objectives are on the world stage. Without clear positions and objectives, the EU will not be able to represent its member states and citizens as effectively as it should.

Проводится сравнительный анализ оперы Дж. Пуччини «Турандот» и пекинской оперы «Принцесса Турандот», который выстраивается на основе оппозиции Запад-Восток. Целью исследования является изучение специфических особенностей пекинской оперы, осуществляемое в опоре на историко-стилевой и культурологический подходы. В ходе исследования доказывается, что принципиальное несовпадение западного классического образца и пекинской версии истории о китайской принцессе определяется разностью культурных традиций, в опоре на которые формируется менталитет творческой элиты Запада и Востока. Теоретическая новизна обусловлена выявлением культурных отличий, обнаруживаемых в таком синтетическом жанре музыкального искусства, как западная опера и пекинская опера. Практическая значимость состоит в возможности использовать полученные данные в процессе интерпретации и реинтерпретации сказки К. Гоцци не в контексте оперного творчества, но и в рамках мирового художественного наследия, частью которого выступает спектакль «Принцесса Турандот». Поставленный в 1922 году Е. Вахтанговым, он и сегодня остается в репертуаре театра, вызывая восторг у публики. The paper presents a comparative analysis of the operas “Turandot” and “Princess Turandot”, which is built on the basis of the West-East opposition. In one case, we are talking about the creation of G. Puccini, in the other - about the Peking opera. The aim of the research is to study the specific features of the Peking opera, carried out in reliance on the historical, stylistic and culturological approaches. The study proves that the fundamental discrepancy between the Western classical model and the Peking version of the story about the Chinese princess is determined by the difference in cultural traditions, on the basis of which the mentality of the creative elite of the West and the East is formed. The theoretical novelty of the study is due to the identification of cultural differences found in such a synthetic genre of musical art as Western opera and Peking opera. The practical significance of the research lies in the possibility to use the obtained data in the process of interpretation and reinterpretation of C. Gozzi's fairy tale not in the context of operatic creativity, but also within the framework of the world artistic heritage, of which the play “Princess Turandot” is a part. Staged in 1922 by E. Vakhtangov, it remains in the theater's repertoire today, delighting the audience.
