What caused/causes cyclone to loose steam? Is it due to (a)opposing westerlies? (b)unfavorable sea temperatures? (c)lack of trees/deforestation/global warming? (d) Can this be reversed just like man can induce rain using seeding, weak cyclone can be forced to make landfall into water starved Tamil Nadu? It is quite interesting to note that all weather models predicted vigorous rains for TN during December (EL NINO, wet MOJO) but nature seems to defy all predictions. Last year we had cyclone NISHA, which provided strong rain for TN, but this year TN missed 2 cyclones - ALIYA and WARD. What explanation can be given for above?

Dear isszet,
[1] As such the upper westerlies will not hamper (much) the growth of a cyclone, instead it will make it to recurve in NEly direction.
[2] Unfavourable sea surface temperature may be one of the reasons that it loses its moisture flux.
[3] Deforestation or felling of trees - NOTHING to do with the formation development of a cyclone.
However one must be bit cautious in answering global warming.
[4] Weather Modification has not been attempted any where in the world: that too on cyclones. Technology has not so much developed to capture a desired weather modification.
If we ruthlessly rupture the weather then it will become a WEAPON OF MASS DESTRUCTION [WMD].
[5]Tropical weather is too tricky to be accureately modeled. However this will be over come very soon.

I agree with you. Regarding point(4)

- Sometimes technology of mass benefit can become mass destruction. For instance nuclear energy(provides energy as well as build atom bombs), genetic cloning (treating diseases, food production as well as wrong clone can mutate randomly) ....
But sometimes good can out weigh bad. Many time drought facing Asian countries have no rains, people die of starvation - these tropical coasts with high probability carry low pressures, depressions - if these can be brought inland - tons of water can be provide great relief. Anyway as u say this kind of scientific modeling and research is yet to be carried out.
