The Indian summer monsoon is strongly influenced by the northward shift of the Intertropical Convergence Zone (ITCZ) over the Indian subcontinent, drawing in moisture-laden winds from the Indian Ocean.
Explanation:
Radiation fog forms on clear, calm nights when the ground radiates heat, cooling the air near the surface to its dew point, causing condensation and fog. It is common in valleys and basins.
Explanation:
The Chinook is a warm, dry wind that blows in the Canadian Prairies and the United States, particularly on the eastern slopes of the Rocky Mountains.
Explanation:
Wind backing is a counterclockwise change in wind direction with altitude in the Northern Hemisphere (e.g., from south to east). Backing typically indicates cold air advection.
