A. The difference in sea level pressure between the Atlantic and the Pacific
B. The difference in sea level pressure between Tahiti and Darwin
C. The difference in sea level pressure between the Azores and Iceland
D. The difference in sea level pressure between the Arctic and the Antarctic
Answer: Option B
Solution (By JKSSB Mock Tests)
The Southern Oscillation Index (SOI) is a measure of the difference in sea level pressure between Tahiti (central Pacific) and Darwin (northern Australia). A negative SOI indicates El Niño conditions, while a positive SOI indicates La Niña conditions.
Explanation:
Tropical maritime air masses are warm and humid, originating over warm tropical oceans. They bring warm, moist, and often unstable weather, leading to convection and precipitation.
Explanation:
Advection fog forms when warm, moist air moves over a colder surface (like a cool ocean or snow-covered ground), cooling the air to its dew point and causing condensation.
