Test: Climate- 2 - Question 10

What is the cause of snowfall in the Himalayas during the winter season?

Detailed Solution for Test: Climate- 2 - Question 10
Cause of snowfall in the Himalayas during the winter season:
There are several factors that contribute to snowfall in the Himalayas during the winter season. The most significant cause is the influence of Western disturbances.
1. Western disturbances:
- Western disturbances are extratropical storms that originate in the Mediterranean region and move eastwards towards the Indian subcontinent.
- These disturbances bring cold and moist air from the Mediterranean Sea, resulting in the formation of clouds and precipitation.
- When these disturbances interact with the Himalayan mountain range, they are forced to rise, causing condensation and subsequent snowfall.
- The higher altitudes of the Himalayas enhance the chances of snowfall during winter.
Other factors that can contribute to snowfall in the Himalayas, although to a lesser extent, include:
2. Advancing monsoon:
- During the summer monsoon season, warm and moist air masses move towards the Himalayas from the Indian Ocean.
- As these air masses rise over the mountains, they cool and condense, leading to rainfall in the lower altitudes.
- In the higher reaches of the Himalayas, this precipitation can fall as snow during the winter season.
3. Retreating monsoon:
- Towards the end of the monsoon season, the withdrawal of the Indian monsoon results in the movement of weather systems from east to west.
- These systems can bring moisture and precipitation to the Himalayas, leading to snowfall.
4. Bay of Bengal Branch:
- The Bay of Bengal Branch is a weather system that brings moisture from the Bay of Bengal towards the Himalayas.
- This moisture can contribute to snowfall in the Himalayas during the winter season.
Overall, the primary cause of snowfall in the Himalayas during the winter season is the influence of Western disturbances. However, other weather systems such as the monsoon and the Bay of Bengal Branch can also play a role in contributing to snowfall in the region.

Test: Climate- 2 - Question 12

Monsoon rainfall increases suddenly and continues constantly for several days. What is this phenomenon known as?

Detailed Solution for Test: Climate- 2 - Question 12
Phenomenon of Monsoon Rainfall Increase
The phenomenon of sudden and continuous increase in monsoon rainfall for several days is known as a burst of the monsoon. This intense rainfall event is characterized by heavy downpours and can have significant impacts on the local climate and environment. Here is a detailed explanation of this phenomenon:
1. Burst of the Monsoon:
- The burst of the monsoon refers to a sudden onset of heavy rainfall during the monsoon season.
- This phenomenon occurs when there is a rapid intensification of the monsoon winds and atmospheric conditions, leading to an increased influx of moisture and convective activity.
- The burst is often accompanied by thunderstorms, strong winds, and a significant rise in humidity levels.
2. Duration and Impact:
- The burst of the monsoon typically lasts for several days to a week.
- During this period, the rainfall is continuous and can be quite heavy, resulting in localized flooding and waterlogging.
- The increased rainfall contributes to the replenishment of water bodies, such as rivers, lakes, and reservoirs, which is crucial for agriculture and water supply.
3. Importance:
- The burst of the monsoon is a critical phase in the monsoon cycle as it helps to break the initial dry spell and kickstart the monsoon season.
- It plays a crucial role in determining the overall monsoon rainfall distribution and its impact on various sectors like agriculture, hydroelectric power generation, and water resources.
4. Regional Variations:
- The burst of the monsoon can vary in timing and intensity across different regions.
- In some areas, it may occur earlier in the monsoon season, while in others, it may be delayed.
- The intensity of the burst can also vary, with some regions experiencing heavy rainfall for a shorter duration, while others may have prolonged periods of continuous rainfall.
In conclusion, the phenomenon of sudden and continuous increase in monsoon rainfall for several days is known as a burst of the monsoon. This event is crucial for the monsoon season as it marks the onset of heavy rainfall, replenishes water bodies, and influences various sectors dependent on rainfall.

Test: Climate- 2 - Question 15

Which of the following statements about the decrease in rainfall is correct?

Detailed Solution for Test: Climate- 2 - Question 15
Explanation:
The correct statement about the decrease in rainfall is:
B: There is a decrease in rainfall generally from east to west in the Northern Plains.
Reasoning:
- The Northern Plains are a region in which the general trend of rainfall is from east to west.
- As we move from east to west in the Northern Plains, there is a gradual decrease in rainfall.
- This decrease in rainfall can be attributed to factors such as the distance from moisture sources, the influence of mountain ranges, and prevailing wind patterns.
- The eastern parts of the Northern Plains receive more rainfall due to their proximity to moisture sources such as the Bay of Bengal.
- As we move towards the western parts of the Northern Plains, the rainfall decreases due to the rain shadow effect caused by the Himalayan mountain range.
- Therefore, the correct statement is that there is a decrease in rainfall generally from east to west in the Northern Plains.
Conclusion:
The correct statement about the decrease in rainfall in the Northern Plains is that there is a decrease in rainfall generally from east to west.
Test: Climate- 2 - Question 16

India receives most rains from

Detailed Solution for Test: Climate- 2 - Question 16
India receives most rains from the southwest monsoon.
The southwest monsoon is responsible for bringing the majority of rainfall to India. It is a seasonal wind pattern that brings moisture-laden winds from the Indian Ocean to the subcontinent. Here are the reasons why the southwest monsoon is the primary source of rainfall in India:
1. Seasonal Wind Pattern: The southwest monsoon occurs during the summer months, typically starting in June and lasting until September. During this time, the monsoon winds blow from the southwest, carrying moisture over the warm Indian Ocean and bringing rainfall to India.
2. Geographical Factors: India's location plays a significant role in receiving rainfall from the southwest monsoon. The country is surrounded by the Arabian Sea and the Bay of Bengal, which provide a moisture source for the monsoon winds. The Western Ghats mountain range and the Himalayas also influence the monsoon pattern by acting as barriers and causing orographic rainfall.
3. Monsoon Trough: The southwest monsoon is associated with the formation of a low-pressure area known as the monsoon trough. This trough acts as a focal point for the convergence of moisture-laden winds, leading to widespread rainfall across the country.
4. Impact on Agriculture: The southwest monsoon is vital for India's agriculture, as it provides water for irrigation and supports the growth of crops. The monsoon rains replenish reservoirs, rivers, and groundwater, which are essential for sustaining agriculture in the country.
In conclusion, the southwest monsoon is the primary source of rainfall in India. Its seasonal wind pattern, geographical factors, formation of the monsoon trough, and its impact on agriculture make it the most significant contributor to India's rainfall.

Test: Climate- 2 - Question 18

By the beginning of August, the monsoon withdraws from the Northern Plains.

Detailed Solution for Test: Climate- 2 - Question 18
False
The statement "By the beginning of August, the monsoon withdraws from the Northern Plains" is incorrect. Here's a detailed explanation:
1. Monsoon Season: The monsoon season in India typically starts in June and lasts until September. During this time, the country experiences heavy rainfall, especially in the northern and northeastern regions.
2. Northern Plains: The northern plains of India, including states like Punjab, Haryana, Uttar Pradesh, and Bihar, are known for their fertile agricultural land and are part of the monsoon region.
3. Monsoon Withdrawal: The withdrawal of the monsoon refers to the retreat of the rainfall activity from a particular region. It usually begins in September and gradually moves southwards, affecting different parts of the country at different times.
4. Northern Plains and Monsoon Withdrawal: The monsoon withdrawal from the northern plains typically occurs in September or even later. By the beginning of August, the monsoon is still active in this region, and heavy rainfall can be expected during this time.
5. Weather Patterns: During early August, the northern plains continue to receive rainfall as the monsoon remains in full swing. The withdrawal process usually starts from the northwest parts of India and gradually progresses towards the southeast.
In summary, the monsoon does not withdraw from the northern plains by the beginning of August. Instead, heavy rainfall can be expected during this time as the monsoon season is still active in the region. Therefore, the statement is false.
