What all were the social, economic, geographical, environmental and technological factors that were an advantage for Kochi International airport compared to the rest of the world ? The major points are listed here.
It is observed that the farther one is from the equator and between the Tropic of Cancer (22.5N) and Tropic of Capricorn (22.5S), the higher the intensity of solar radiation received. The earth axis' tilt of 23.5 deg causes regions around the Tropic of Cancer and Capricorn to receive normally directed solar radiations, having a higher intensity of radiation. ( this is because normally incident rays travel less distance through the earth's atmosphere, gets less scattered and transfers more energy to land). Kochi (10N latitude) and Bangalore (12N latitude) for that instance, would naturally be having lesser solar radiation than Dubai (25N latitude).
Another contributing factor as to why Kochi and Bangalore are having low solar irradiance values is the impact of monsoons, South West and North East (a unique meteorological-geographical phenomenon observed only in South India in the whole world) which lowers the solar irradiance intensity in South India due to cloud cover and heavy rains from June to October every year.
Besides if Kochi airport is also able to expand its physical infrastructure by building new terminals to overtake Delhi (handling 40 m passengers and a space of 5.5 million sq ft) and Mumbai (handling 36 m passengers and area of app 5 million sq ft), the present third largest international terminal in the country at Kochi will get noticed for its worthwhile efforts. It will herald a new dawn for Kochi airport. Kochi also may become the low-cost preferred first airport of landing for foreign airlines flying into the country.
