Abstract. Monitoring drought and mastering the laws of propagation are basis for regional prevention resistance. Multivariate indicators considering meteorological, agricultural hydrological information may fully describe conditions. However, series variables in cold arid regions that too short or missing make it difficult to monitor drought. This paper proposed a method combining Soil Water As...

in this study, a new array of meteorological elements and a synoptic climatologic classification to produce abaseline climate and to derive meteorological factors that are effective on air pollution in tehran, which is located in a semi-enclosed basin was developed. the data set includes daily sea-level pressure and 500mb geopotential height fields from ncep-ncar and tehran upper air sounding d...

Drought in South Asia affect food and water security and pose challenges for millions of people. For policy-making, planning, and management of water resources at sub-basin or administrative levels, high-resolution datasets of precipitation and air temperature are required in near-real time. We develop a high-resolution (0.05°) bias-corrected precipitation and temperature data that can be used ...

A distributed land-surface model is used to simulate the seasonal cycle of snow cover for a high-latitude basin. In comparison with the distributed model, a simulation using surface parameters and meteorological data averaged over the entire basin overestimates the peak snow accumulation and underestimates the duration of snow cover. Dividing the basin into a small number of elevation bands and...

Agro-meteorological index insurance can transfer the risks in the agricultural production, reduce the farmers' economic losses, and promote a sustainable development of agricultural production. However, traditional agricultural insurance with a single rate has the problems of the presence of adverse selection, the difficulty of determining premium rates and assessing the claims. As a new agricu...

Today, the need for water sources is swiftly increasing due to population growth. At the same time, it is known that some regions will face with shortage of water and drought because of the global warming and climate change. In this context, evaluation and analysis of hydrological data such as the observed trends, drought and flood prediction of short term flow has great deal of importance. The...

[1] Severe droughts developed in theWest and Southeast of the U.S. starting early in 2007. The development of the droughts is well monitored and predicted by our model-based Drought Monitoring and Prediction System (DMAPS). Using the North America Land Data Assimilation System (NLDAS) realtime meteorological forcing and the Variable Infiltration Capacity (VIC) land surface model, DMAPS is capab...

Drought is a major problematic phenomenon for the mostly semi-arid country of Iran. The north centralregions of Iran (north of Esfahan and Ghom province) have suffered from severe droughts several times duringthe last three decades. The frequent occurrence of drought in these regions is due to low and inconsistentprecipitation, abnormally high temperatures, increases in surface albedo and evapo...

Yunnan suffered from a severe drought from Winter, 2009 to Spring, 2010. Compared with traditional methods for drought monitoring, remote sensing (RS) based methods has the merits of almost real-time and large covering area. In this paper, vegetation water supply index (VWSI) was used to detect the drought condition utilizing Moderate Resolution Imaging Spectroradiometer (MODIS) data in Yunnan ...
