Vant geostrofic


Vantul geostrofic

 Avand in vedere ecuatia generala de miscare a aerului atmosferic se poate concluziona ca miscarea orizontala (vantul geostrofic) se poate trata separat de miscarea verticala.

Din ecuatia generala se neglijeaza forta centrifuga, (atmosfera considerandu-se in miscare uniforma, rectilinie si orizontala), se neglijeaza fortele de frecare, acceleratia relativa.

 Astfel asupra particulei de aer ar mai actiona numai forta Coriolis si forta gradientului baric- aproximatia geostrofica .

 Cea mai simpla aproximatie pentru o atmosfera in miscare este aproximatia geostrofica a vantului, in care miscarea si circulatia aerului se considera la scara mare sinoptica.

Vanturi geostrofice sunt toate miscarile aerului de mare amploare:

-circulatia in cicloni si anticicloni

-alizeele

-circulatia generala a atmosferei

-musonii

Vantul geostrofic este apropiat de vantul real numai in atmosfera libera, unde nu intervin fortele de frecare.Circulatia reala se abate mereu de la echilibrul geostrofic, datorita, mai ales, fortei Coriolis. Forta gradientului baric actioneaza perpendicular pe izobare dinspre presiuni mari spre cele mici. Astfel, in emisfera nordica vantul geostrofic este paralel cu izobarele, presiunea scazuta regasindu-se la stanga. In emisfera sudica, presiunea scazuta se afla la dreapta vantului geostrofic. La ecuator viteza vantului geostrofic este maxima si descreste spre poli in conditiile aceluiasi gradient baric.
