WORLD WEATHER THREAD

A look at monsoons:

This visualization uses a combination of NASA satellite data and models to show how and why the monsoon develops over this region:


In the summer the land gets hotter, heating the atmosphere and pulling in cooler, moisture-laden air from the oceans. This causes pulses in heavy rainfall throughout the region. In the winter the land cools off and winds move towards the warmer ocean and suppressing rainfall on land.

GPM is joint mission between NASA and the Japanese Aerospace Exploration Agency (JAXA).

Haven't seen much in Western media of this yet, a lot of people seem to be in a "eh, first storm of the season" sort of mood, but this is bigger than the one (Soudelor) last year that was pretty horrible.

We'll send you some of our water. Had a years worth of rain in July, pretty much a thunderstorm every day. August we had more rain in the first week than the entire average month... Was great for my garden and new grass. :p

Tree leaves are starting to yellow now, as the nights are getting cold (6 degrees), but still 20+ in the daytime. :D
