“…Qualitatively there was a change that indicated a significant increase in summer precipitation, and a decrease in the number of annual frosts, concentrating the winter season (July and August), assuming a "tropicalization of the region". Rainfall tropicalization can be understood as local and regional processes and impacts of climate change, which can be observed mainly by changes in the precipitation regime and the intensification of tropical climatic characteristics [57]. This process is not exclusive of Espinal Ecorregion.…”

In central Argentina, the annual rainfall regime shows increasing since the 2nd half of the 20th century. The aim of this work was to evaluate the long-term changes in the intensity of rainfall in the central-north region of Entre Ríos between 1945 and 2019, based only on daily precipitation records aggregated at yearly, monthly and seasonal levels. We used monthly rainfall data for the period 1945–2019 from 6 localities in Province of Entre Rios, Argentina. The change detection analysis has been conceded using Pettitt’s test, von Neumann ratio test, Buishand’s range test and standard normal homogeneity (SNH) test, while non-parametric tests including linear regression, Mann-Kendall and Spearman rho tests have been applied for trend analysis. Like the regional results, this study observed a sustained increase in monthly rainfall to the breaking point in the 1970s, but then the annual rate of increase was even higher. The average annual rainfall in the region prior to that date was 946 mm, while after the same 1150 mm, equivalent to 21.5% higher than the 1945–1977 average and 8.5% higher according to the historical average 1945–2019.

“…The frontal weather system (atmospheric fronts) not only plays a key role in the weather variability in the mid-latitudes but is regularly linked with high-impact weather episodes e.g., wind, gusts, hail, or precipitation [17]. Procedures for automatic objective frontal analysis [18][19] frequently depend on the definition of a thermal frontal parameter. Several regional and global climatology depend on the processed thermal front parameter approach [20][21] along with trend analyses for the past, recent, and future forecasts e.g., [22][23].…”

Pakistan, which is positioned in the South Asian sub-continent, occupies a significant climatological location. It is included among the world's few countries which experience a comprehensive transformation from summer all the way to winter season. The variation in precipitation has direct and significant consequences on society. In this ongoing research, the latitudinal variation in the track of the frontal system and trends in Pakistan during the monsoon period have been examined. Meteorological data (monthly rainfall, maximum temperature, satellite images, upstream data for Tarbela, Mangla, Rasool, and Marala) has been taken to conduct the ongoing research. Consequently, the focus of the study is the frontal weather system that moves North of Pakistan and energizes the monsoon rainfall over the Indus Basin which makes it a source of flooding. The rainfall is the cause of flooding downstream of rivers in the plains of Punjab and Sindh. Varying trends in rainfall were observed across the selected stations in Pakistan. The ongoing research is conducted across Pakistan with Gilgit and Skardu being the cities in Northern Pakistan. Among all the water reservoirs, Tarbela exhibited an increased upstream flow due to the snow melt factor over glaciers in Gilgit and Skardu because of an increase in maximum temperature.

“…No noroeste do estado do Paraná, conforme zoneamento agrícola é possível a semeadura dessa leguminosa nos meses de julho a agosto (primeira safra) e de fevereiro a março (terceira safra) (IAPAR, 2021). Nessa região, apesar da maior ocorrência de chuvas no verão (segunda safra) (NASCIMENTO JÚNIOR et al, 2020), as temperaturas acima de 30ºC limitam o cultivo do feijão nesse período (MASSIGNAM et al, 2017).…”

RESUMOO trabalho teve como objetivo determinar os índices de produtividade do feijão irrigado e não irrigado, conduzido em dois sistemas de cultivo. O delineamento experimental foi em parcelas subdivididas em faixas, com quatro repetições, dois níveis do fator sistema de cultivo (com e sem mobilização do solo) e cinco níveis do fator reposição de água (0, 42, 61, 100 e 138% da lâmina líquida). O manejo da irrigação foi realizado por meio de balanço hídrico, com reposição de água através de uma linha de aspersores. Após a colheita, as variáveis respostas (produtividade de grãos, massa de 100 sementes, número de vagens por planta e número de grãos por planta) foram analisadas estatisticamente. As produtividades nos sistemas de cultivo com (2.280,3 kg ha -1 ) e sem (2.389,2 kg ha -1 ) mobilização do solo, não apresentaram diferenças estatísticas. Entretanto, a distribuição irregular das chuvas, fez com que a produtividade máxima (3.313,1 kg ha -1 ) na condição irrigada superasse em 81,6% a condição de sequeiro (609,9 kg ha -1 ). O cultivo de sequeiro seria economicamente viável apenas quando a relação de preços entre o milímetro de água e o quilograma do feijão fosse superior a 41,2 kg mm -1 . PALAVRAS-CHAVE: manejo de irrigação, reposição de água, sistema de cultivo.
