#1. In S hemisphere if an observer faces wind, low will be to his ____
In the Southern Hemisphere, facing the wind, the low pressure area is to the right due to Coriolis deflection.
#2. In N hemisphere due to rotation of earth winds are deflected to
In the Northern Hemisphere, moving air is deflected to the right due to Earth's rotation, so relative to motion it appears left.
#3. Local Winds follow Buys Ballots law
Local winds, like sea breeze and mountain winds, generally follow Buys Ballot’s law relating wind direction and pressure system.
#4. Coriolis force acts perpendicular to the _____ of wind direction in N hemisphere.
Coriolis force in the Northern Hemisphere deflects moving air to the right of its path, perpendicular to motion.
#5. Geostrophic wind is due to the balance between the forces
Geostrophic wind occurs when the pressure gradient force is balanced by the Coriolis force, resulting in flow parallel to isobars.
#6. Coriolis force is strongest at
Coriolis effect is zero at the equator and maximum at the poles due to Earth's rotation geometry.
#7. Geostrophic rule breaks down at
At the equator, Coriolis force is negligible, so geostrophic balance does not apply effectively.
#8. Fohn winds are ____ on the Leeward side of a mountain.
Föhn winds warm and dry due to adiabatic compression on the leeward side after rising over mountains.
#19. Anabatic wind is stronger than katabatic
Anabatic winds, caused by daytime heating along slopes, are stronger than nocturnal katabatic winds.
#20. Katabatic wind is down slope cold wind due to nocturnal cooling
Katabatic winds result from cooled dense air descending slopes at night.
