Arctic Basin pressure system switchover, on schedule

~A helpful defence against complete meltdown of all Arctic sea ice


   Arctic Ocean pressure system summer switchover occurs when Arctic cyclones persist over colder areas, as opposed to winter hugging over warmer sources, such as open sea water.  It is a phenomenal counter melting action, which saves sea ice extinction.   It turns out to be also,  a bearer of more Arctic rains on the Canadian  Arctic archipelago, furthering the detriment of permafrost,  which when warmed furthers the presence of Anticyclones which persist over warm sources in Arctic summers.    The reverse 
scenario, may happen,  such as during summer 2007, when a High Pressure system persisted over the Arctic Ocean gyre area, exacerbating the sea ice melting a great deal, even of very thick sea ice, this was likely a dynamic pressure blocking scenario, or just as much from an extreme heat wave over Arctic lands spilling over to sea,  which invites the presence of a steady High pressure system 

   CMC surface analysis, June 13 2025 00 UTC.  A Gyre Low, counters the normal Gyre clockwise current, which was powered by many winter months of a steady High pressure system.  It is characterized by colder temperatures,  likely sustained by clouds, which are a plenty when warm moist air streams over colder sea ice. The clouds and sea ice maintain a colder surface than adjoining areas bombarded with sun rays to the surface. I see the Great North Pacific warm temperature blob as the main source of moisture sustaining this balance of clouds.   Of Course, the North Atlantic , equally warmer, is another source.

   The rain onslaught is starting, only an extreme heat wave can break this from happening. WD June 13, 2025.
