the effect of the global warming and the troposphere and oceanic warming changes causing to these unexpected extreme weather conditions.

moreover, I would like to notify the Infrastructure drainage system's importance in Qatar to prevent the flood in future. there are many tunnels under construction for railways and they must be considered about future extreme rainfalls as the global atmosphere & weather conditions not stable. heavy rain and storm can hit anytime because of the oceanic warming. 2015 is on record for warmest year.
so, Infrastructure and drainage systems must be considered and they should planed depend on the height from the sea level. concentration in this angle may lead the rain water to drain faster and can provide the disasters in future.
