[MISSION 2023] RTM(Revision through MCQs)- 5 May 2023

Ans: (d)

Explanation:

• Arctic warming and jet stream migration
• The Arctic is warming three to four times faster than the globe as a whole, meaning there is ever less difference between northern temperatures and those closer to the equator.
• That is resulting in swings in the North Atlantic jet stream, which in turn leads to extreme weather events like heatwaves and floods.
• Heat domes
• Warmer oceans contribute to heat domes, which trap heat over large geographical areas. The heat dome is stretching from the southern plains of the Oklahoma/Arkansas area all the way to the eastern seaboard, according to the U.S. Weather Prediction Center.
• Scientists have found the main cause of heat domes is a strong change in ocean temperatures from west to east in the tropical Pacific Ocean during the preceding winter.
• As prevailing winds move the hot air east, the northern shifts of the jet stream trap the air and move it toward land, where it sinks, resulting in heatwaves.
• El Niño and La Niña
• Every few years, the climate patterns known as El Niño and, less frequently, La Niña occur. El Niño brings warm water from the equatorial Pacific Ocean up to the western coast of North America, and La Niña brings colder water.
• At present, La Niña is in effect. Because summer temperatures trend lower during La Niña, climate scientists are concerned about what a serious heatwave would look like during the next El Niño, when even hotter summer weather could be expected.

Ans: (b)

Explanation:

• Most cyclones are forced to weaken post landfall as they detach from the sea.
• Cyclones are formed between the tropics while western disturbances are formed in the mid-latitudes. When the two interact, they influence each other. When cyclones come under the influence of western disturbances, it can retain its intensity even after entering land.
• Cyclone Tauktae in 2021 came under the influence of western disturbances, it slowed down as it was crossing over to land. This slow progress over the coast ensured that the cyclone continued to get sufficient moisture supply from the sea. Hence it did not weaken, but rather retained its intensity even 24 hours after coming over land.
• The Bay of Bengal and the Arabian Sea generate only 7 per cent of the world’s cyclones. However, their impact are huge as some of the most densely populated regions of the world, including some mega-cities, are susceptible.
