The present warming developments within the Arctic may perhaps shove the Arctic procedure right into a seasonally ice-free kingdom no longer noticeable for a couple of million years. The melting is accelerating, and researchers have been not able to spot traditional approaches that may sluggish the deicing of the Arctic. Such monstrous extra melting of Arctic and Antarctic glaciers and ice sheets might elevate the ocean point around the globe, flooding the coastal parts the place some of the global s inhabitants lives. stories, led via scientists on the nationwide heart for Atmospheric study (NCAR) and the collage of Arizona, exhibit that greenhouse fuel raises over the subsequent century may hot the Arctic by way of 3-5°C in summertime. hence, Arctic summers through 2100 should be as hot as they have been approximately 130,000 years in the past, whilst sea degrees ultimately rose as much as 6 m better than today.

This phenomenon was confirmed by analysis of microwave satellite measurements started in 1978 (Belchansky et al. 2005). Ice melting led to abrupt changes in heat and radiation budgets at the boundary air-sea surface due to albedo rapid decreasing. That in turn accelerates various feedbacks including energy exchange processes. Heat fluxes from sea surface to atmosphere over free of ice areas of Kara and Laptev Seas appeared in autumn during last 3 years probably caused a large-scale depression in atmospheric pressure field over Northern Asia and changes in atmospheric circulation regimes.
1999). The similar conclusion follows from the statistical analysis of polar mesoscale cyclones (PMCs) over the North European Basin using cloud cover distribution data for 1981–1995 (Mokhov et al. 2007). It was shown that the cumulative frequency distribution of mesocyclones is well approximated by an exponential function in a size range from 50 to 400 km. This result suggest that a substantial amount of heat, moisture and momentum flux at the air-sea interface is likely may be missing from the reanalysis (Condron et al.
The September–November SAT (°C) trend for a site Salekhard (66° N, 67° E). Discussion and conclusion Presented results proved that the Atlantic-Arctic climate system components are closely interrelated. Moreover, fluctuations in the Atlantic SST modulated corresponding oscillations in many other subsystems: Eastern Arctic ice extent, land surface pressure, SST in shelf seas, surface air temperatures in North Asia. The key to the new climate change outlook is the natural cycle of ocean temperatures called the Atlantic Multidecadal Oscillation (AMO), which is closely related to the warm currents that bring heat from the tropics to the shores of Europe.
