Increased Rain fall in tropics.

A new study based in part on NASA satellite data has shown that an increase in large, well-organized thunderstorms is behind increased rainfall in the wettest regions of the tropics. Joint research from the Australian Research Council Centre of Excellence for Climate System Science (ARCCSS) and NASA published online in Nature today reveals that rainfall increases seen in places such as the western Pacific in recent decades are actually due to large storms – what the authors call “organized deep convection” – happening more frequently, rather than from individual storms producing more rain.
