Answer: Option B
Solution (By JKSSB Mock Tests)
The Pacific-North American (PNA) pattern is a climate pattern that affects the western United States and Canada, influencing temperature, precipitation, and storm tracks across the region.
Explanation:
The warm, dry summers of a Mediterranean climate are caused by the subtropical high-pressure belt shifting poleward during summer, bringing sinking dry air and stable conditions.
Explanation:
The polar jet stream forms due to the strong temperature contrast between polar air and tropical air, creating a steep pressure gradient and strong winds, which are then deflected by the Coriolis force.
