O conhecimento da variabilidade temporal das chuvas, possibilita prever mudanças no sistema hidrológico, planejar e gerenciar os recursos hídricos locais. Assim, objetivou-se avaliar a variabilidade temporal da precipitação pluvial e, realizar o Balanço Hídrico Climatológico (BHC), visando a caracterização da disponibilidade hídrica face às mudanças nos padrões de chuva do município de Chimoio, Moçambique, como também, classificá-lo climaticamente. Para isso, foram obtidos dados diários de precipitação pluvial e temperatura média do ar para o período de 1989 a 2018. A variabilidade da precipitação foi avaliada mediante a aplicação do Desvio Padronizado da Precipitação, teste sequencial de Mann-Kendall e regressão linear. Por meio do BHC foram determinados: deficit hídrico (DEF), excesso hídrico (EXC), retirada de água do solo (RET), reposição de água da chuva ao solo (REP), evapotranspiração real (ETR) e evapotranspiração potencial (ETP). A classificação climática foi obtida por meio dos índices: hídrico (Ih), aridez (Ia), umidade (Iu) e eficiência térmica (Iet). A precipitação pluvial de Chimoio não apresentou mudanças significativas no seu comportamento. Contudo, verificou-se grande oscilação, com valores anuais variando de 546,6 mm a 1724 mm, e média de 1016,63 mm. Observou-se um DEF anual de 240 mm entre abril e novembro, EXC de 226,4 mm e REP 96,4 mm entre dezembro e janeiro. O clima foi caracterizado como C2 B’3 s2 w a’. Os resultados obtidos poderão subsidiar o desenvolvimento de políticas públicas voltadas ao gerenciamento dos recursos hídricos, além de mitigar impactos ocasionados pela variabilidade da chuva no município de Chimoio, Moçambique.  Temporal analysis of rainfall and climate water balance for the municipality of Chimoio, MozambiqueA B S T R A C TThe knowledge of the temporal variability of rainfall makes it possible to foresee changes in the hydrological system, to plan and manage local water resources. The objective was to evaluate the temporal variability of rainfall and to carry out the Climatic Water Balance (CWB), aiming to characterize water availability in the face of changes in rainfall patterns in the municipality of Chimoio, Mozambique, as well as to classify it climatically. For this purpose, daily rainfall data and average air temperature were obtained for the period from 1989 to 2018. The variability of precipitation was assessed by applying the Standardized Precipitation Deviation, Mann-Kendall sequential test, and linear regression. The CWB determined: water deficit (WD), water surplus (WS), removal of water from the soil (RWS), replacement of rainwater to the soil (RRS), actual evapotranspiration (AET) and potential evapotranspiration (PET). The climatic classification was obtained by means of the indices: water (Iw), aridity (Ia), humidity (Ih), and thermal efficiency (Ite). The Chimoio rainfall did not show significant changes in its behavior. However, there was a large oscillation, with annual values ranging from 546.6 mm to 1724 mm, and an average of 1016.63 mm. An annual WD of 240 mm was observed between April and November, WS of 226.4 mm, and RRS 96.4 mm between December and January. The climate was characterized as C2 B'3 s2 w a'. The results obtained can support the development of public policies aimed at the management of water resources, in addition to mitigating the impacts caused by the variability of rainfall in the municipality of Chimoio, Mozambique.Keywords: water deficit, climatic classification, climate changes, Mann-Kendall.

Abstract: The objective of this work was to estimate the coffee supply by calibrating statistical models with economic and climatic variables for the main producing regions of the state of São Paulo, Brazil. The regions were Batatais, Caconde, Cássia dos Coqueiros, Cristais Paulista, Espírito Santo do Pinhal, Marília, Mococa, and Osvaldo Cruz. Data on coffee supply, economic variables (rural credit, rural agricultural credit, and production value), and climatic variables (air temperature, rainfall, potential evapotranspiration, water deficit, and water surplus) for each region, during the period from 2000-2014, were used. The models were calibrated using multiple linear regression, and all possible combinations were tested for selecting the variables. Coffee supply was the dependent variable, and the other ones were considered independent. The accuracy and precision of the models were assessed by the mean absolute percentage error and the adjusted coefficient of determination, respectively. The variables that most affect coffee supply are production value and air temperature. Coffee supply can be estimated with multiple linear regressions using economic and climatic variables. The most accurate models are those calibrated to estimate coffee supply for the regions of Cássia dos Coqueiros and Osvaldo Cruz.

The hydrology section is divided into two main components, surface and groundwater. One of the most important outcomes in the water balance equation for any natural area or water body is Evapotranspiration and it is also a crucial component of the hydrologic cycle. Prediction of monthly evapotranspiration can be obtained depending on observed monthly average temperatures at a meteorological station in each year. Calculating of water balance in Iraq depending on meteorological data and Thornthwaite method was the aim of this research. Results of corrected potential evapotranspiration (PEc) obtained from applying Thornthwaite formula were compared with annual and monthly rainfall in thirty two meteorological station in order to estimate actual evapotranspiration (AE). The results showed that the annual summation of rainfall increased from south west towards north east according to the increasing ratio of rainfall due to the impact of Mediterranean climate condition on Iraq. Actual evapotranspiration depends directly on water excess during calculating water balance. Water surplus contour map indicates increased values towards north-east direction of Iraq, where water surplus depends directly on both rainfall and actual evapotranspiration.

Studies of water balance have been carried out for Ranchi taking 35 years (1970-2004) of climate data. Ranchi has annual water need of 1754 mm, rainfall of 1460 mm, actual evapotranspiration (AE) of 860 mm, water surplus (WS) of 600 mm and water deficit (WD) of 894 mm. The aridity index values were analyzed to assess the frequency of drought experienced of this region. The study reveals that during the above period, Ranchi has experienced 11 percent of large drought and severe drought, but only 3 per cent disastrous droughts in 35 years. Moderate drought category is observed to be most common with 23 per cent probability. Analyses of periods will contagious drought indicate that during the five year period 1980-84 and 1995-99, moderate, large and severe droughts were experienced.

As a result of the statistical analysis of the meteorological and water balance data for Onego Lake watershed over the period 1950-2000, noticeable changes were detected. It was found that time series of annual air temperature, precipitation and evapotranspiration over 50-year period contains positive linear trends, but no change in total streamflow to the lake has so far followed. Potential changes in the regional climate and hydrological regime for the period 2000-2050 were estimated using the results of numerical modeling with the ECHAM4/OPYC3 model for two scenarios of the global climate change. The estimation of these data shows that a general tendency to increase of annual air temperature and precipitation will remain in the new climate Mean annual precipitation will increase about 30-50 mm, mean average annual air temperature for the next 50-years period will rise from 1.6 up to 2.7-3.0 °C. Our estimation shows that for both scenarios all water balance parameters, excluding river runoff, will increase.

However, its production is highly climate dependent. The objective of this study was to estimate maize yield by calibrating statistical models for the state of Mato Grosso do Sul - MS. The cities studied were Chapadão do Sul, Costa Rica, Ponta Porã and Sidrolândia. The climatic variables used were air temperature, rainfall, potential evapotranspiration, deficit and excess water from 2003 to 2017 between February and May. The models were calibrated and compared by the KNN and RANDOM methods. The accuracy and precision of the models were analyzed by the mean percentage error and the adjusted determination coefficient, respectively. The variables that most influenced corn production were water deficit and air temperature. It is possible to estimate corn yield with multiple linear regressions using climate variables. Chapadão do Sul and Costa Rica have high levels of water deficit, while Ponta Porã and Sidrolândia have low deficits. The most accurate model for estimating maize yield in cities was the RANDOM method.   Keywords: Climate; Yield; Modeling.

Abstract The paper discusses the course of air temperature in the years 1961-2014 in Chojnice (Central European Lowland), and its effect on water temperature and occurrence of ice cover on Lake Charzykowskie. An increase in mean annual air temperature was determined by 0.31°C per 10 years, and its even faster increase in the winter season (December-March), by 0.37°C per 10 years on average. An increase in mean annual water temperature in the lake by 0.24°C per 10 years also occurred. An increase in air and water temperature in winter months caused a reduction of the period of occurrence of ice cover. In the years 1961-2014, the persistence of ice cover was subject to a decrease by 3.7 days per 10 years on average, and the mean thickness of the ice cover decreased from 30 to 19 cm.
