Answer: Option B
Solution (By JKSSB Mock Tests)
A derecho is a widespread, long-lived wind storm associated with a line of severe thunderstorms (squall line) that produces damaging winds over a large area.
Explanation:
The Coriolis effect deflects winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to Earth's rotation.
Explanation:
A negative AO phase is characterized by higher than normal pressure over the Arctic and lower than normal pressure over the mid-latitudes. This allows cold Arctic air to spill southward, leading to colder winters in the mid-latitudes.
