Think of a petrifying situation when all you can see around is water covering miles and miles of land surface! It is being observed by many scientists across the globe that if the level of average temperature rises by around 40C over the next hundred years, the intensity of rainfall will rise by around 25%. Some of the places of the Asian monsoon region and other places all across the globe are expected to witness a greater increase in the level of rainfall whereas, the smaller increases will be experienced by the regions of South Africa, Australia and the Mediterranean.
Experts have stated by now; the drastic changes in precipitation levels all around the globe can be exhibited by observing the fluctuations in the flow and strength of local winds. As a particular region warms up because of human-induced carbon emissions, the winds loft that moisture-laden air through the atmosphere where you will be able to condense and precipitate down to the surface. However, these fluctuations will also influence intensity most of the extreme rainstorms of the region.
The Globe in a Bird’s Eye View
Change in rainfall pattern is one of the effects of global warming, that is quite prominent and precise. Since the 19th century, meteorologists and scientists have predicted that the intensity of heavy rain events will increase with the stipulated rise in average temperature all across the globe. The recent observations which, have been observed so far reflect a similar trend as well on a global, broad scale. However, understanding how the extreme storms will fluctuate on a specific, saturated place has become quite tricky for the experts to resolve as because weather data is not available across all the countries or continents.
Scientists have made significant efforts to decipher the factors that influence the region-to-region fluctuations in terms of increasing density of rainfall. They have observed that the fluctuations in flow of winds and not water vapour is responsible for the precipitation variations from region-to-region.
A rapid decrease in the amount of rainfall over the subtropical ocean regions has been observed as one the effects of global warming where the atmosphere is mostly dry and produce weak storm systems on a relative basis. Experts have stated that this might be due to the continual expansion of tropical areas and related changes to the atmospheric circulation system. As the weather has warmed over the past decade, it has been noted that climate pattern at the equator has shifted across the poles and has created a wider tropical belt.
Climate pattern all across the globe is going through a paradigm shift and the precipitation patterns are also changing. Thus, the real quest is to do the least we can to promote a sustainable living, reduce degradation of natural resources and reduce the impact of global warming which, will further balance out the random fluctuations in precipitation patterns across the globe.
