Leh Cloudburst: What caused it? The Most Plausible Theory



There are many presumptive theories floating around on what triggered the Leh Cloudburst. Some are on the lines of conspiracy theories like those attributing it to Chinese  targeting the country with their weapon modification program. Others sound seemingly outright outlandish being attributed to UFO activities. Still there are others blatantly anti-Green, accusing massive reforestation and afforestation drives over the decades as being responsible for the disaster. 

Some simply end up stirring a controversy, like those blaming the disaster on on global warming. The remaining theories suggest the disaster was caused by natural climatic phenomena. However, these still fall short of offering a complete synoptic explanation of what forces actually caused the strong updraft and downdraft that led to the cloudburst in the first place.

If we need to crack the Leh Cloudburst in order to adequately and scientifically explain it, then we must identify what forces were behind both the strong updraft and downdraft. We examined seven major theories in attempt to understand which among them appeared most plausible.

Cloud Motion Vector

This latest cloud motion vector depicts the movement of clouds along the wind. It indicated the strength of Wind at Tibet. It may be inferred that North Coastal AP, Orissa Coast, South Bihar and to some extend South AP and North Coastal districts of TN may get rainfall.

Tibetian High strengthening




Tibetian High is strengthening. Upper level winds from this high drags the cloud in NEly / Easterly direction along the path of High Pressure winds. And clouds are forming in middle tropospheric level [say at 500 hPa level] and these clouds were dragged along the upper air wind originating from High Pressure in Tibet. The strong lower level SWM winds above 15 Degree latitude becomes higher level easterly / NEly and becomes divergence.
It has been ascertained from the previous satellite imagery during last week [ from 23.08.2010 to 26.08.2010.] That is why NE states are NOT getting rainfall and Capital Delhi was getting unusual rainfall in Aug.
This is one sort of interpretation. Please comment on it.
