Which of the following are the characteristics of weather in the India...
- As the summer sets in and the sun shift northwards, the wind circulation over the subcontinent undergoes a complete reversal at both, the lower as well as the upper levels. By the middle of July, the low-pressure belt nearer the surface, (termed as Inter Tropical Convergence Zone (ITCZ), shifts northwards, roughly parallel to the Himalayas between 20° N and 25° N. Hence statement 1 is correct.
- By this time, the westerly jet stream withdraws from the Indian region. In fact, meteorologists have found an interrelationship between the northward shift of the equatorial trough (ITCZ) and the withdrawal of the westerly jet stream from over the North Indian Plain. Hence statement 2 is not correct.
- At the upper level, an easterly jet stream flows over the southern part of the Peninsula in June and has a maximum speed of 90 km per hour. In August, it is confined to 15°N latitude, and in September up to 22° N latitude. The easterlies normally do not extend to the north of 30° N latitude in the upper atmosphere. Hence statement 3 is not correct.

Which of the following are the characteristics of weather in the India...
Characteristics of Weather in the Indian Subcontinent in the Summer Season:
Weather patterns in the Indian subcontinent during the summer season exhibit specific characteristics that play a crucial role in determining climatic conditions. Let's explore these characteristics in detail:
Intertropical Convergence Zone shifts to 20° N and 25° N:
- The Intertropical Convergence Zone (ITCZ) is a belt of low pressure near the equator where trade winds converge, typically bringing heavy rainfall.
- During the summer season, the ITCZ shifts northward to around 20° N and 25° N in the Indian subcontinent.
- This shift leads to the onset of monsoon rains in the region, bringing relief from the scorching heat and replenishing water sources.
Withdrawal of Easterly Jet Streams:
- Jet streams are fast-flowing narrow air currents found in the upper atmosphere.
- During the summer season, the easterly jet streams, which typically influence weather patterns in the region, start to weaken and withdraw.
- This withdrawal of easterly jet streams plays a role in the onset of the monsoon season and the shift in weather patterns across the Indian subcontinent.
Onset of Westerly Jet Streams on the Peninsula:
- As the easterly jet streams weaken and withdraw, the westerly jet streams start to make their presence felt over the Indian peninsula.
- The onset of westerly jet streams brings changes in wind patterns and atmospheric conditions, contributing to the overall weather dynamics during the summer season.
In conclusion, the characteristics of weather in the Indian subcontinent during the summer season, including the shift of the ITCZ, withdrawal of easterly jet streams, and onset of westerly jet streams, play a significant role in shaping the climatic conditions and precipitation patterns in the region.
