Furthermore, the interannual variation of summer precipitation is attributable to the variation of heavy rainfall frequency over the HRV. The heavy rainfall frequency, in turn, is influenced by sea surface temperature anomalies (SSTAs) over the north Indian Ocean, equatorial western Pacific, and the tropical Atlantic. The tropical SSTAs modulate the HRV heavy rainfall events by influencing atmo...

Based on the daily precipitation data from 53 meteorological stations, 11 extreme precipitation indices were selected, categorized and calculated; the temporal and spatial patterns in these indices and their teleconnections with the large-scale circulations were analyzed by the non-parametric Mann-Kendall test; and Sen’s slope estimator and linear regression for the period of 1960–2014 were cal...

Gridding of daily precipitation data alleviates many of the limitations of data that are derived from point observations, such as problems associated with missing data and the lack of spatial coverage. As a result, gridded precipitation data can be valuable for applied climatological research and monitoring, but they too have limitations. To understand the limitations of gridded data more fully...

The attribution of the observed shift in precipitation extremes to different forcing agents represents a critical issue for understanding changes in the hydrological cycle. To compare the effects of aerosols and greenhouse gases on the historical trends of precipitation intensity, we have performed the National Center for Atmospheric Research/Department of Energy Community Atmosphere Model vers...

Precipitation is a key aspect of the climate system. In this paper, the dependability of five satellite precipitation products (TRMM [Tropical Rainfall Measuring Mission] 3BV42, PERSIANN [Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks] CDR, GSMaP [Global Satellite Mapping of Precipitation] RENALYSIS, CMORPH [Climate Prediction Center’s morphing techni...

introduction occurrence of heavy and rainstorm events is among the characteristics of arid and semi-arid regions all over the world and particularly in iran which is causing large floods and debris town. how ever, they can be used to supply and store water by controlling and exploiting the run off water floods. indexes of atmospheric instability are very useful scientific instruments to underst...
