Medium Resolution Spectral Imager (MERSI) on board the new Generation Polar-Orbiting Meteorological Satellite of China (FY-3) has five spectral channels with 250m spatial resolution, which enhances the ability to observe fine surface features and provides a new data source for drought monitoring in large area. Drought status of north China is evaluated using FY-3A/MERSI satellite data with Perp...

hydrological drought analysis using sdi index in halilrud basin of iran abstract nowadays, drought is considered as damaging environmental phenomenon which affects natural resources and social communities. therefore it will be an important issues that magnitude and effects of these phenomena to be considered. to do this we used l-moment method for regional homogeneity testing. the streamflow dr...

The paper describes a new software package for automated estimation, display and analyses of various drought indices – continuous functions of precipitation that allow quantitative assessment of meteorological drought events to be made. The software at present allows up to five different drought indices to be estimated. They include the Decile Index (DI), the Effective Drought Index (EDI), the ...

The deficiency and uneven distribution of rainfall during the 2009 monsoon has brought several issues to the fore: rising water demand from various sectors, regional effects of a drought and the failure of the India Meteorological Department to provide credible forecasts at the disaggregate level. A multi-pronged strategy to permanently deal with monsoon deficiency requires exploring newer drou...

Agriculture is a sector easily affected by meteorological conditions. Crop yield reduction, even regional conflicts, may occur during a drought. It is extremely important to improve the state of our knowledge on agricultural drought risk. This study has proposed a new method (vulnerability surfaces) for assessing vulnerability quantitatively and continuously by including the environmental varia...

Lack of access to insurance exacerbates the impact of climate variability on smallholder famers in Africa. Unlike traditional insurance, which compensates proven agricultural losses, weather index insurance (WII) pays out in the event that a weather index is breached. In principle, WII could be provided to farmers throughout Africa. There are two data-related hurdles to this. First, most farmer...

Various drought monitoring models have been developed from different perspectives, as drought is impacted by various factors (precipitation, evaporation, runoff) and usually reflected in various aspects (vegetation condition, temperature). Cloud not only plays an important role in the earth's energy balance and climate change, but also directly impacts the regional precipitation and evaporation...
