Makahiki-puni i loko o ka Arctic cyclones hoʻomōhala. Anticiklonʻeleu puleʻAmelika, i loko o ka hooilo, oiai i loko o ke kau, ka mea, ua hoʻoneʻe i loko o ka huina me ka Moana Pākīpika. Cyclones rampage ma ka ?? eoi? O ke kauwela. Manawa a hiki i kēia loli, ka Polar hau pono hōʻike likeʻole o ka lewa puʻe. Winter mau mai November a hiki i April, kau - mai June a hiki i Augate. Ma waho originated ma ka moana cyclonesʻaneʻi pinepine hele cyclones i hele mai mai waho.

I ka makani? Eia ma ka North Pole mea iʻaʻahu, akā, i ka mämä holo o luna o 15 m / s kokoke 'aʻole i kānāwai. Makani ma luna o ka Arctic Ocean advantageously i ka mämä holo o ka 3-7 m / s.
Kaʻawelike i loko o ka hooilo - +4 i -40 kau - mai ka 0 a hiki i +10 kekelē Kelekia.

Low ao mai i kekahi periodicity i loko o ka papa o ka makahiki. Iloko o ke kauwela, me ka likelihood o haʻahaʻa ao hiki 90-95% ma ka hooilo - 40-50%. Mea Makamae hou typical no ke anu wa. Summer ka noe i pinepine, i kekahi manawa ole lakou e ku mai i ka pule.

Ii iai, typical o keia wahi - hau. Ua aneane e ole e hiki mai, a ina ka mea e, i ka nui pinepine ia me ka hau. Haule makahiki 80-250 mm o, ma ka aina o 'Eulopa akau o ka Arctic kīʻaha - he iki hou.

Ke aniau o ka kikowaena māhele mea softer ma mua i loko o nā wahi e pili ana (kokoke i na kapakai o ka hawaiian hapa o Eurasia a me North America). ʻO wai komo iloko o ka mahana au paialewa o ka 'Akelanika, a hana i ka lewa o ka holoʻokoʻa wai kahi o ka moana.
