This study aims to examine the variability of rainfall and temperature based on spatio-statistical analysis. Data for the study was gotten from the Nigerian Meteorological Agency and subjected to statistical analysis using mean, standard deviation, time series analysis, t-test and correlation. The results of the study revealed that the mean rainfall in the area is 108.6 mm, mean temperature is 28o C and mean sunshine is 4.7 hours. The result further revealed that mean onset date in the state is 13th march, mean cessation date is 10th October while the mean length of rainy season is 223 days. The result also showed that rainfall anomaly index in the area ranged between -2.12 and 2.28 while temperature anomaly ranged between -2.31 and 1.73.  The correlation coefficient showed that cessation (0.408) and Length of rainy season (0.406) is significantly related to rainfall, sunshine hours (0.380) and Average temperature (0.867) is significantly related to minimum temperature, sunshine hours (-0.389) and average temperature (0.749) is significantly related to maximum temperature while onset (-0.642) and cessation (0.509) is significantly related to length of rainy season. However,there is a significant difference in onset dates, cessation dates and length of rainy season in the area. The area is experiencing a significant increase in temperature, rainfall and sunshine hours and recommends that more tress should be planted in the area and Nigerian meteorological agency should also inform farmers about the onset of the rains so as to help the farmers prepare for the planting season.

O aumento de temperatura do ar é uma realidade inquestionável. Vários trabalhos em macroescala confirmam esse fato, mas é preciso melhorar nossa compreensão, também, em escalas menores. O objetivo desse estudo foi analisar e comparar as normais climatológicas das temperaturas máxima, mínima e média compensada do período de 1961-1990 (normal de referência) com as normais climatológicas provisórias de 1994-2015, com o propósito de identificar mudanças nos padrões de temperatura e obter uma avaliação mais refinada das mudanças climáticas ocorridas nas últimas décadas no estado do Ceará, Brasil. Para tal, utilizou-se do banco de dados meteorológicos do INMET. O comportamento das temperaturas máxima, mínima e média compensada revelou para todas as estações selecionadas, um padrão de aumento do período 1994-2015 em relação ao período 1961-1990, da ordem de 0,7 oC, 0,4 oC e 0,6 oC em média, respectivamente. Destaca-se que esse aumento alcançou todo o estado mas, como cada localidade apresenta particularidades, a alta da temperatura não foi uniforme variando em função do setor do estado. As temperaturas médias foram “puxadas” para cima mais por conta dos aumentos das temperaturas máximas do que devido às medidas das temperaturas mínimas.Palavras-chave: Aquecimento do Ar; Normais Climatológicas; Mesoescala.  Space-Time Analysis of Temperatures in Ceará in the Context of Climate Change  A B S T R A C TSpatiotemporal analysis of temperatures in Ceará-Brazil in the context of climate change. The rise in air temperature is an unquestionable reality. Several studies in macroscale confirm this fact, but we must improve our understanding also at smaller scales. The aim of this study was to analyze and compare the climate normals of maximum, minimum and average temperature of the 1961-1990 period (normal reference) with the provisional climate normals from 1994 to 2015, with the purpose of identifying changes in temperature patterns and a more refined assessment of climate change over the past decades in the state of Ceará. For this, the database is used, taken from the National Meteorological Institute of Brazil (INMET). The behavior of the maximum, minimum and average temperature revealed for all selected stations, a pattern of increased period 1994-2015 for the period 1961-1990, in the order of 0.7 °C, 0.4 °C and 0.6 oC in average, respectively. It is noteworthy that this increase reached throughout the state but as each location has special features, the temperature rise has not been uniform. It changed due to the state section. Average temperatures were "pulled" up more because of the rise in maximum temperatures that due to the measures of minimum temperatures.Keywords: Air Warming, Climate Normals, Mesoscale.

Climate change as certain phenomena has occurred globally and the impact feels by people especially for those who live on the island. Weather pattern shifting is one of the evidence of climate change impact, and many scientists are still trying to prove it. Weather affected by a combination of temperature, relativity humidity, etc. The fact that those parameters closely related to the need of health especially temperature and relative humidity and well-known thermal scale grouped in a range called discomfort index (DI). This study aims to analyze the outdoor condition in Bandar Lampung by figure out discomfort index. Weather parameter collected from secondary data of Teluk Betung weather station from 2007 – 2017 in three levels of high, average and low condition. In that period, temperature and humidity in Bandar Lampung relatively stable between 20-35∘C and 50-100%. In general, the city encountered with varies conditions by high temperature above 29∘C and high relative humidity more than 85%. Meanwhile, DI changes from year to year are not significantly occurred that indicates in high temperature, average and low weather are everyone feels severe stress, more than 50% of people feel discomfort, and comfortable condition. Nevertheless, every year it already shows an uncomfortable situation especially in high temperature and even at an average temperature. Furthermore, the study needs to compare with other weather stations in Bandar Lampung.

The health office is in charge of instructing and registering diarrhea sufferers in each region, then the area will be evaluated which areas are most affected by diarrhea. And checking directly into the field revealed that the most basic cause was about the unclean environment such as trenches that were too much garbage, causing floods during the rainy season. The health office also encourages the community to always maintain environmental cleanliness and familiarize people to always wash their hands with soap before eating and after cleaning with simple things like this is expected to help reduce diarrhea sufferers in the city of Medan. K-Medoids Clustering is clustering algorithm which is similar to K-Means. The difference between these two algorithms is the K-Medoids or PAM algorithm uses the object as a representative (medoid) as the center of the cluster for each cluster, while the K-Means uses the mean (mean) as the center of the cluster.Keywords: Diarrhea, Service office, Data mining, K-Medoids Algorithm

ABSTRACT The study measures rainfall data to determine a rainwater harvesting coefficient revelant to rainwater harvesting and catchment projects assisted by non-parametric statistics tests, based on assumption that part of the total rainfall depth is discarded. The analyses of historical rainfall series shows that the city of Belem presents large potential to promote rainwater harvesting, with a rainy season and a less rainy season during the year. The results present an average of one rainfall event per day, from January 2001 to December 2011, and of which around 38% is used only for washing the rainwater harvesting system. The Anderson-Darling test revealed a non-adherence of the rainfall series to a normal distribution and according to the Mann-Kendall test, there was no significant trend in the evaluated series. After the calculation of the effective rainfall, determination of coefficients, application of the Anderson-Darling normality test and the Kruskal-Wallis variance test, it was proposed a rainwater harvesting coefficient of 0.78 for the city of Belém, Brasil.

The Lancang-Mekong River is an important international river in Southeastern Asia. In recent years, due to climate change, natural disasters, such as drought and flooding, have frequently occurred in the region, which has a negative effect on the sustainable development of the social economy. Due to the lack of meteorological monitoring data in the six countries across the region, the study of the characteristics of climate change in this area is still scarce. In this paper, we analyze the characteristics of climate change in the Lancang-Mekong sub-region (LMSR) during 2020–2100 based on the climatic data of CMIP5, using the linear trend rate method, cumulative anomaly method, the Mann–Kendall test, and Morlet wavelet analysis. The results showed that the annual mean temperature and annual precipitation in the LMSR increased significantly. The annual average temperature in this area increased at a rate of 0.219 °C/10a (p < 0.05) and 0.578 °C/10a (p < 0.05) in the RCP4.5 and RCP8.5 scenarios, respectively; the annual precipitation in the area was 29.474 mm/10a (p < 0.05) and 50.733 mm/10a (p < 0.05), respectively. The annual average temperature in the region changed abruptly from low to high temperatures in 2059 for the RCP4.5 scenario and 2063 for RCP8.5. The annual precipitation in the area changed from less to more in 2051 for the RCP4.5 scenario and 2057 for RCP8.5. The results of wavelet analysis showed that the annual mean temperature in the LMSR had no significant change period at the 95% confidence level under the scenario of RCP4.5 and RCP8.5. Under the scenario of RCP4.5 and RCP8.5, the annual precipitation had a significant 3.5-year and 2.5-year periodicity, respectively. Extreme climate events tended to increase against the background of global warming, especially in high emission scenarios.

Parques urbanos servem como áreas de lazer e práticas de exercício, levando a preocupação do conforto térmico de seus usuários. O Parque Mãe Bonifácia, objeto deste estudo, encontra-se na cidade de Cuiabá-MT, sendo um fragmento de cerrado urbano, sofrendo com toda a sazonalidade do clima local, tendo períodos de seca rigorosa e períodos com precipitação. Assim, o objetivo deste trabalho foi fazer uma análise da variação espaço-sazonal termohigrométrica pelo método da krigagem do referido Parque. Foram feitas medidas mensais de temperatura do ar e umidade relativa do ar nos horários entre às 10 e 12 horas. No período seco, as médias de temperatura do ar foram de 33,44 oC, já a média de temperatura para o período chuvoso foi de 31,09 oC. A média de umidade relativa do período seco foi de 43,34% e para período chuvoso 68,71%. Como resultado se percebeu a influência do entorno no parque, sendo as menores temperaturas do ar e maiores umidades relativas do ar as que ocorrem na região central do parque. Os ajustes dos semivariogramas foram considerados satisfatórios para 3 dos 4 períodos analisados, encontrando dificuldade em realizar o ajuste para a umidade relativa do ar no período chuvoso, tendo como a presença da água um possível causador dessa dificuldade. Para os dados de microclima do município de Cuiabá-MT, os resultados estão de acordo com as normais climatológicas e outros estudos realizados na mesma região.Palavras-chave: Semivariograma.

Mãe Bonifácia Park, object of this study, is in the city of Cuiabá-MT, being a fragment of urban cerrado, suffering with all the seasonality of the local climate, having periods of strict drought and periods with precipitation. Thus the objective of this work was to make an analysis of the space-seasonalthermohygrometric variation through the kriging method of the aforementioned park. Monthly measurements of air temperature and relative humidity were taken at times between 10 and 12 hours. In the dry period the averages of the air temperature were 33.44oC, whereas the average temperature for the rainy period was 31,09oC. The mean relative humidity of the dry period was 43.34% and for the rainy season 68.71%. As a result the influence of the surroundings in the park was observed, being the lowest air temperatures and the hightest relative humidity of the air occurring in the central region of the park. The adjustments of the semivariograms were considered satisfactory for 3 of the 4 analyzed periods, finding it difficult to adjust for the relative humidity of the rainy season, with the presence of water being a possible cause of this difficulty. For the microclimate data of the municipality of Cuiabá-MT, the results are in agreement with the climate normals and other studies carried out in the same region.Keyword: Semivariogram.

This study investigated the boreal digging frog, Kaloula borealis, to determine the egg hatching period and whether the hatching period is affected by incubation temperature. The results of this study showed that all the eggs hatched within 48 h after spawning, with 28.1% (±10.8, n=52) hatching within 24 h and 99.9% (±0.23, n=49) within 48 h after spawning. A significant difference was noted in the mean hatching proportion of tadpoles at different water temperatures. The mean hatching rates between 15 and 24 h after spawning was higher at a water temperature of 21.1 (±0.2) °C than at 24.1 (±0.2) °C. These results suggest that incubation temperature affected the early life stages of the boreal digging frog, since they spawn in ponds or puddles that form during the rainy season.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

This chapter addresses the cultural politics, history and revival of Vietnamese court orchestras, which were first established at the beginning of the Nguyễn dynasty (1802–1945). Based on fieldwork in the city of Hue, it considers the decolonizing processes that have enabled Vietnamese court orchestras to take their place alongside other East Asian court orchestras as a display of national identity in the global community of nations. The metaphor of ‘orchestrating the nation’ is used to refer to the ways in which Vietnamese orchestras have been harnessed for sociopolitical ends in several historical periods. Court orchestras as heritage have recourse to a generic, precolonial past, yet they are not entirely uncoupled from local roots. Through a case-study of the revival of the Nam Giao Sacrifice, a ritual for ‘venerating heaven’, the chapter addresses the dynamics of interaction and exchange between staged performances of national heritage and local Buddhist and ancestor worship rituals. It argues that with growing concern about global climate change, the spiritual and ecological resonances of the Nam Giao Sacrifice have provided opportunities for the Party-state to reassert its position as the supreme guardian of the nation and its people.
