Assignment#1

Diffusing a Super Cyclone by degrading it to a normal oceanic depression!Like “Taming a wild elephant”

Super cyclone and its horrific impacts are well known especially for those residing in coastal areas of India. Now a days, the Met department is somewhat accurately able to monitor and forecast the cyclones using satellite data and advanced technologies. Its formation, movements and timing etc. are closely being tracked, but the focus is somehow to manage the cyclone and its impacts after it makes a landfall. There is no step that has been taken in the direction to reduce the intensity before it becomes a super cyclone. Can we somehow diffuse the cyclone by reducing its intensity or change its direction such that the life and financial damage is minimized, or can it be broken down into multiple smaller parts so that the intensity is reduced. Longer, the cyclone remains above sea it captures more moisture and its intensity increases. Can somehow it be pushed towards the nearest land area by changing its direction so that it loses its power, or can its kinetic power be preserved or transformed for normal human usage. Unfortunately, no such major scientific breakthrough has been achieved so far in this direction.

A super cyclone is basically formed from a tropical oceanic depression in Indian ocean. While normal depressions are desirable to get the required amount of rain fall in the coastal areas, their transformation into super cyclones are the most disastrous ones. In 1999 Odisha super cyclone was the most intense super cyclone in the Indian ocean damaging $4.44 billion, 30,000 fatalities, wide spread flooding, damaging 1.6 million homes (source: wiki). Several cyclones have hit coastal India like Laila, Nilam, Helen, Lehar, Hudhud, Fani etc. just to name a few. States like Tamil Nadu, Andhra Pradesh, Odisha, Wet Bengal have repeatedly been coming under red alert during these cyclones. Dec 2016, Vardha super cyclone crossed eastern coast of India close to Chennai caused $3.35 billion damage leaving hundreds of deaths and thousands of homeless. Recently in April 2019 Fani an extremely sever cyclonic storm strike, coast of Odisha, AP, WB, Sri Lanka due to which 1.2 million residents from vulnerable coastal areas have been evacuated and rehalbitated causing $1.8billion damage and an estimation shown $11 billion would be required for the restoration process.
Personally, I have witnessed three cyclones including 1999 super cyclone. Every time the news comes about cyclone there is fear and panic, how the millions of people will be evacuated. How suddenly people would leave their village, animals and all their belongings to move to another place. The wind speed at more than 250 KM per hour destroys almost everything, it uproots several trees, towers, buildings. Many villages and towns get disconnected with rest of the world in terms of communication and it takes months to get back the electricity but still it takes years for the life to come back to normalcy. Fatalities during the cyclone is high and the post impact is also sever as it follows major flooding and post flooding problems.
Some of the major achievements that Indian government has been able to achieve in terms of mass evacuation, reduce life casualties to almost zero, rehalbitation, relief process, and faster restoration etc.  But still today in many places these measures are not adequate. May be more due diligence, planning and pre-preparation would be required. Even after so many cyclonic impacts, there is no initiative for underground electrification, quick restoration of basic needs including drinking water.
  
India is not alone; many other countries globally face such storms and cyclones time to time. In Pacific and Atlantics typhoon and hurricanes make even bigger damage to mankind. The global climate change including atmospheric composition, global average temperatures, ocean conditions, and others can be blamed for such events.
Some research has shown that the green house effect, EI Nino phenomenon etc has increased the intensity and frequency of such oceanic storms and cyclones and we are going to face more number of such devastations in twenty first century!
Therefore, scientists, researchers, geologists, international communities and everyone have to come together to find better solution towards solving this challenge in a better way. May be innovative business models, could bring the required thrust and inquisite towards finding the right solution of this problem.

Some of the methods proposed over Internet by many people and scientists across the globe:
Method #1: Fly Supersonic Jets in to the eye of super cyclone



No guarantee, this can not be made with a demo – How can you compare the power of a couple F-14s with 10^13 Watts. Flying at eyewall the turbulence is a great way to destroy a couple of airplanes and end the lives of their pilots.

Method #2: Use a Giant Funnel to Divert Warm Water into the Ocean
I think the warm water will always try to go up (that’s natural) in contrast to how it is shown in the video that the warm water will flow down inside the funnel. Not sure what mechanism the funnel should have and how many such funnels required.

Method #3: Seed super cyclones/hurricanes with silver iodide, in the hopes of strengthening the clouds around the hurricane and creating an "outer eyewall." 

Method #4: Blowing the hurricane apart with hydrogen bombs

Method #5: Bombard Lasers

Why it is not solved yet?
  • Complex and expensive – experiments or demo to conduct not easy!
  • As massive amount of energy swirling around, how would you measure if your method has some positive or negative impact or not.
  • These are "massive geophysical events" whose size and complexity are even bigger than most people realize. So, is it better not to mess around with complex geophysical phenomena without knowing what we're doing?
  • It might create an effect that's worse than the problem that we are trying to solve.
  •  With our current state of knowledge, we are still not able to accurately predict which depressions will turn to super cyclone, as I said before all oceanic depressions are not bad, in fact they are required for maintaining the required level of rain fall and moisture level in the coastal areas.
  • Is the real answer is "to focus on living with nature rather than trying to do gee whiz science to modify super cyclones."
