Explanation: The rainfall during the monsoon season in India is significantly influenced by depressions formed over the Bay of Bengal.
9) Rainfall occurs all over the country during monsoon when
a) Axis of MT is in its normal position along Gangetic plains
b) Axis of MT is along Himalayas
c) Depression has formed over Bay of Bengal
Explanation: When the axis of the monsoon trough (MT) is positioned normally along the Gangetic plains, it leads to widespread rainfall across India.

a) Gangetic plains
b) foot hills of Himalayas
c) Bay of Bengal
Explanation: A break in the monsoon usually occurs when the axis of the monsoon trough shifts towards the foothills of the Himalayas, leading to reduced rainfall in the plains.
11) With a depression over the head Bay fair weather during monsoon occurs over
a) Assam
b) W Bengal
c) Orissa
Explanation: Fair weather is often observed in West Bengal when a depression is present over the head Bay during the monsoon season.
12) Monsoon is also called
a) NE monsoon
b) SW monsoon
c) SE monsoon
Explanation: The term "monsoon" primarily refers to the southwest monsoon in the context of India, which is crucial for its rainfall.
13) Post monsoon weather period is
a) Mar to May
b) Jun to Sept
c) Oct to Nov
d) Jan to Feb
Explanation: The post-monsoon weather period in India is typically characterized by the months of October to November, following the southwest monsoon season.
14) During post monsoon, pressure gradient over India is
a) weak
b) steep
c) same as winters
Explanation: During the post-monsoon period, the pressure gradient over India is generally weak, leading to less turbulent weather.
15) During monsoon period, low pressure lies over
a) Bay of Bengal
b) NE India
c) Central India
d) Pakistan
Explanation: During the monsoon period, a low-pressure area is typically established over the Bay of Bengal, which influences rainfall patterns.
16) During vigorous monsoon period the pressure gradient over west coast is
a) Weak
b) Steep
c) Normal
Explanation: A steep pressure gradient over the west coast of India during the vigorous monsoon period leads to strong winds and heavy rainfall.
17) An aircraft flying in Monsoon season from Chennai to Kolkata at 14 km will experience winds
a) Easterly
b) Westerly
c) Nly
d) Southerly
Explanation: During the monsoon season, winds at higher altitudes typically shift to westerly due to the southwest monsoon.
18) An aircraft flying in Winter season from Chennai to Kolkata at 12 km will experience winds
a) Ely
b) Wly
c) Nly
d) Sly
Explanation: In winter, the winds at this altitude typically blow from the east (Ely) due to the high-pressure systems over northern India.
19) An aircraft flying in Pre monsoon season from Delhi to Kolkata at 10 km will experience winds
a) Easterly
b) Westerly
c) Northerly
d) Southerly
Explanation: During the pre-monsoon season, winds tend to be westerly at higher altitudes, influenced by changing weather patterns.
20) An aircraft flying in Monsoon season from Mumbai to Ahmedabad at 03 km will experience winds
a) SEly
b) SWIy
c) Nly
d) NWly
Explanation: During the monsoon season, winds near the west coast are generally south-easterly (SEly) due to the influence of the southwest monsoon.
21) An aircraft flying in winter season from Delhi to Kolkata at 06 km will experience winds
a) SEly
b) SWIy
c) Nly
d) NW - Wly
Explanation: In winter, the winds typically blow from the north (Nly) due to high-pressure areas dominating the region.
22) An aircraft flying in winter season from Delhi to Kolkata at 06 km will experience
a) Port drift
b) Starboard drift
c) Tail wind
d) Head wind
Explanation: Port drift occurs when the aircraft is subject to wind pushing it towards the left side (port) while flying in winter winds from Delhi to Kolkata.
23) An aircraft flying in winter season from Kolkata to Nagpur at 02 km will experience
a) Port drift
b) Starboard drift
c) Tail wind
d) Head wind
Explanation: Starboard drift is likely to occur due to the prevailing winds when flying from Kolkata to Nagpur in winter.
24) During break monsoon, the pressures all over the country
a) Rise
b) Fall
c) Do not change
Explanation: During a break in the monsoon, the atmospheric pressures across the country typically rise, leading to drier conditions.
25) During break monsoon, sometimes the surface winds over East UP and Bihar are
a) very strong
b) weak
c) normal
Explanation: In some cases during the break monsoon, surface winds in regions like East UP and Bihar can become very strong due to localized pressure systems.
26) Mid tropospheric cyclone occurs during
a) Pre monsoon
b) Winters
c) Post monsoon
d) SW monsoon
Explanation: Mid-tropospheric cyclones are more likely to form during the pre-monsoon period, contributing to weather variability.
27) Mid tropospheric cyclone during monsoon forms over
a) Orissa
b) Punjab
c) Gujarat
d) Chennai
Explanation: During the monsoon, mid-tropospheric cyclones are typically observed to form over Gujarat due to favorable atmospheric conditions.
28) El Nino episode is applied by fishermen (of Ecuador and N Peru) to a period of reduced fish catch due to suppression of upwelling
a) warm surface coastal current
b) Wly surface coastal current
c) Cold surface coastal current
Explanation: The El Niño phenomenon is characterized by a warm surface coastal current that suppresses the upwelling of nutrient-rich cold waters, affecting fish populations.
29) Maximum cyclones occur over India in
a) Pre monsoon
b) Winters
c) Post monsoon
d) SW monsoon
Explanation: The highest frequency of cyclones in India typically occurs during the pre-monsoon period, particularly in the Bay of Bengal region.
