This study revisits the question posed by Hoskins on why the Northern Hemisphere Pacific sea level pressure (SLP) anticyclone is strongest and maximally extended in summer when the Hadley cell descent in the northern subtropics is the weakest. The paradoxical evolution is revisited because anticyclone buildup to the majestic summer structure is gradual, spread evenly over the preceding 4–6 mont...

Abstract Seasonal and interannual variations of chlorophyll- a (chl- ) in the upper Gulf Thailand (uGoT) were obtained using new regionally tuned algorithms applied to Moderate Resolution Imaging Spectroradiometer-Aqua. This long time-series (2003–2017) data analyzed context environmental conditions associated with Southeast Asian Monsoon. Chl- distribution patterns distinct for non-monsoon (NO...

Abstract As an internal forcing of the earth climate system, soil moisture (SM) significantly influences water and energy cycle by controlling evapotranspiration terrestrial solar energy. The current study used observed precipitation, remotely sensed SM, reanalysis atmosphere land parameters to assess East Asian Monsoon (EAM) precipitation variability due meridional SM oscillations across China...

We examined changes in several independent intensity indices of four major tropical monsoonal circulations for the period 1950–1998. These intensity indices included observed land surface precipitation and observed ocean surface pressure in the monsoon regions as well as upperlevel divergence calculated at several standard levels from the NCAR/NCEP reanalysis. These values were averaged seasona...

Water vapor in the lower stratosphere exhibits localized maximum values during Northern Hemisphere summer in the Asian and North American (NA) monsoon regions. The processes maintaining these maxima are not well understood. We analyze the variability of water vapor in the monsoon regions based on Aura Microwave Limb Sounder satellite observations during 2005–2013 and quantify links to deep conv...
