Detailed analysis of the satellite derived water vapour for a five years period (1995-1999) prior to and during southwest monsoon is done over Indian subcontinent adjoining seas. Three layer (1000 hPa – 700 hPa, –500 500 -300 hPa) total moisture data available from NOAA/TOVS are used analysis. These study northward propagating intraseasonal oscillations in tropical Ocean summer season. Results ...

Abstract The influence of Rossby waves emitted in the northeastern Pacific Ocean on Northern Hemisphere’s atmosphere during summer is analysed using ERA5 reanalysis and a new large ensemble performed with EC-Earth3 model. Wave Sources (RWS) trigger wave-like patterns arising from upper troposphere north-eastern region, causing response around Hemisphere alternating regions positive negative cor...

in this paper, the correlation between total ozone and upper air meteorological parameters such as heights of geopotential surfaces and temperatures for three stations of tehran, ankara and bet dagan located in the middle east, in cold period (jan, feb and march) of years of 2005, 2007 and 2008 has been investigated. data for upper air is taken from wyoming university and ozone data is from sat...
