কারণ ও প্রেক্ষাপট

Wind is the horizontal movement of air, driven primarily by pressure-gradient force and modified by rotation and friction. The governing relationship is: Unequal heating creates pressure differences; air accelerates down the pressure gradient, while Coriolis and surface friction alter its speed and direction.

কীভাবে কাজ করে

Unequal heating creates pressure differences; air accelerates down the pressure gradient, while Coriolis and surface friction alter its speed and direction.

মূল তথ্য

• Wind direction is named for where it comes from.
• Geostrophic wind balances pressure-gradient and Coriolis forces above the friction layer.
• Sea breezes develop when land heats faster than adjacent water during the day.
