Rising tropical sea surface temperatures alter atmospheric dynamics at heights of 16 kilometers or more.

Bulk percipitation displays the combined effects of all water soluble components of precipitation. Dust from the earth's surface is commonly assumed to be alkaline; it is commonly reported in the literature as a constituent of the atmosphere and of precipitation.

Annual rainfall, especially during winter and monsoon, has decreased in over 68 per cent of the country, claims a recent study by Indian Institute of Tropical Meteorology (iitm), Pune.

Relative rates of temperature change between the troposphere and surface, and the mechanisms that produce these changes, have long been a contentious issue. Graversen et al.predicated upon the ERA-40 reanalysis, report polar tropospheric amplification of surface warming and attempt to explain this finding dynamically. (Brief Communications Arising)
