The Indian Ocean Dipole (IOD) affects the monsoon by changing:
A. All of the above
B. Sea surface temperatures in the Indian Ocean
C. Jet stream strength
D. Wind patterns over Asia
Answer: Option B
Solution (By JKSSB Mock Tests)
The IOD is a climate pattern characterized by differences in sea surface temperatures between the western and eastern Indian Ocean, which affects monsoon rainfall.
Explanation:
The 'Little Ice Age' (roughly 1300-1850) was a period of cooling in the Northern Hemisphere, thought to be caused by decreased solar activity (sunspot minimums) and increased volcanic eruptions that reduced solar radiation.
Explanation:
The mild, wet winters of a Mediterranean climate are caused by the southward shift of the polar front and mid-latitude cyclones, bringing westerly winds and precipitation.
Explanation:
Sudden stratospheric warming (SSW) is a phenomenon where the polar vortex weakens or splits due to a rapid increase in stratospheric temperatures, often leading to cold air outbreaks in the mid-latitudes.
