We analyze how extreme rainfall intensities in the Eastern United States depend on temperature T, dew point temperature Td, and convective available potential energy CAPE, in addition to geographic sub-region, season, and averaging duration. When using data for the entire year, rainfall intensity has a quasi Clausius-Clapeyron (CC) dependence on T, with super-CC slope in a limited temperature r...

Background and Objectives: Cholera is one of the public health ththat has received attention due to climate change and weather variables. In the current study, the trend of cholera and its epidemics was assessed in the last 50 years in Iran based on climatic variables. Methods: In a retrospective cohort study, all cholera cases and epidemics of the disease in the country (Iran) were assessed u...

This study evaluated the accuracy of several models for estimating daily solar radiation (Q) across Australia. Data from 39 sites were taken from MetAccess. The sites were grouped into four climatic zones. Coefficients of nine models, including two newly developed formulae, were fitted for the 39 sites. Correlation coefficients (R2) between estimated Q and measured Q and root mean squared error...

Rainfall and temperature are important climatic inputs for agricultural production, especially in the context of climate change. However, accurate analysis and simulation of the joint distribution of rainfall and temperature are difficult due to possible interdependence between them. As one possible approach to this problem, five families of copula models are employed to model the interdependen...

A regional climate model named Providing REgional Climates for Impacts Studies (PRECIS) adapted in generating rainfall scenarios for the SAARC (South Asian Association for Regional Cooperation) region. At first, PRECIS generated rainfall scenario is calibrated with ground-based observed rainfall during baseline period (1961-1990) in Bangladesh. The regression coefficients obtained through calib...

waterlogging is one of the problems of cotton-growing in rainy regions which affects adversely plant growth in the early stages. so that rainfall causes waterlogging in early to mid spring in the fields without proper drainage. also, rainfall declines soil and environment temperatures. to investigate the effects of waterlogging period duration and temperature on vegetative properties and glycol...
