typhoon 係anticlockwise,
但係N.hemisphere under Coriolis force唔係deflect to the right咩??

typhoon  係 N.hemisphere 同 S.hemisphere 係唔同轉向架

我知呀!
但點解釋typhoon係N hemisphere係轉左while under Coriolis force應該係deflect to the right??

lawty_1995

coriollis force係deflected to the right OF ITS PATH. the arrow is pointing to the center and it  turn right, so it is anti-clockwise

typhoons 既路徑仲會受 high pressure ridge/ high pressure 影響.  有陣HK食唔正 D 風, 都可能因為 有high pressure developed 係 陸地

abc281007

Coriolis force係受到地球自轉影響的
因為南北半球既deflect方向不同

但其實我唔太明樓主想問d咩
係北半球typhoon點解係anti-clockwise?

since typhoon is a low pressure system.
and wind blows from high pressure to low pressure
if the typhoon situates at the northern hemisphere.
all the wind will be attract to the center of the typhoon
and owing to the effect of Coriolis force
Wind will deflect to its right in the northern hemisphere
then as the wind originally blows into the center and now it deflects to its right
anti-clockwise movement is resulted

個coriolis force佢只喺北半球先至喺咁而南半球就相反
