“Arctic cyclones” are,
obviously, cyclones that occur in the Arctic regions. It is parallel to the
Pacific “typhoons” and the Atlantic “hurricanes”.
Recent news that I read in http://esciencenews.com/articles/2013/12/11/arctic.cyclones.more.common.previously.thought tells of an increase in identified
cyclones in the Arctic, that these cyclones are actually more common than what
is previously thought. Although this does not imply that the actual number of
cyclones in the Arctic has drastically increased in the recent years as
compared to what it might have been hundreds or thousands of years ago, it still
certainly deserves global attention.
There is considerable information about Arctic
cyclones and there is constant monitoring of the ice levels in the Arctic, but
much research still has to be done to connect the dots and know which causes
which and to what extent they do. Probably this phenomenon is still a little
overlooked by most because it is spatially distant to most countries, but the
implications of changes in the patterns in the Arctic will surely affect global
climate.
It might be
helpful to share some information with their corresponding contexts: http://nsidc.org/arcticseaicenews/.
The thing about Arctic cyclones is that, it
does to the ocean waters the opposite of what a tropical cyclone does. While a
tropical cyclone pulls colder water from deep towards the warmer surface, an Arctic
cyclone pulls warmer water towards the colder surface. The cooling of the ocean
in the tropical regions as result of a tropical cyclone might be harmless, but
the warming of the ocean in the Arctic regions brings about the melting of ice,
which obviously cannot be good for, well, the world.
I think that this is not just a concern of the
countries near the Arctic. We know that all have an impact on the global
climate and all are affected by it. The oceans are connected, and a rise in the
sea waters can be really dangerous for low-lying island countries. How will the
international community react? More research has to be done, and action should
result from the findings.
