Which of the following is a major factor in the formation of a lake-effect snow?
A. Warm air moving over a warm lake
B. Cold air moving over a cold lake
C. Cold air moving over a warm lake
D. Warm air moving over a cold lake
Answer: Option C
Solution (By JKSSB Mock Tests)
Lake-effect snow occurs when cold, dry air moves over a relatively warm lake, picking up moisture and heat, which leads to intense convection and heavy snowfall downwind of the lake.
Explanation:
The northeastern states receive heavy rainfall due to the orographic effect of the Himalayas, forcing the moisture-laden monsoon winds to rise and condense.
Explanation:
The Monsoon Trough is a region of low pressure extending from the Thar Desert to the Bay of Bengal, which is crucial for monsoon rainfall.
Explanation:
The Arctic Oscillation (AO) is a large-scale climate pattern of sea level pressure differences between the Arctic and the mid-latitudes of the Northern Hemisphere. It affects weather patterns across the entire Northern Hemisphere.
