Which of the following is a major research facility operated by the Indian Institute of Tropical Meteorology (IITM)?
-
Atmospheric Radiation Measurement (ARM) Facility
-
Indian National Center for Ocean Information Services (INCOIS)
-
National Atmospheric Research Laboratory (NARL)
-
Indian Institute of Geomagnetism (IIG)
A
Correct answer
Explanation
IITM operates the Atmospheric Radiation Measurement (ARM) Facility, a network of ground-based observatories that collect data on atmospheric radiation and aerosols.
What is the recommended relative humidity level for the preservation of most museum objects?
-
30-40%
-
40-50%
-
50-60%
-
60-70%
B
Correct answer
Explanation
A relative humidity level of 40-50% is generally recommended for the preservation of most museum objects, as it helps to prevent damage caused by excessive moisture or dryness.
How do ocean currents influence the formation of fog?
-
By transporting warm, moist air over cooler water
-
By creating areas of low pressure that promote fog formation
-
By releasing water vapor into the atmosphere
-
All of the above
A
Correct answer
Explanation
Ocean currents can influence the formation of fog by transporting warm, moist air over cooler water. As the warm air cools, it condenses and forms fog.
What is the recommended humidity level for a productive workspace?
-
30-40%
-
40-50%
-
50-60%
-
60-70%
B
Correct answer
Explanation
The recommended humidity level for a productive workspace is typically between 40 and 50%, as it helps maintain a comfortable and healthy environment.
-
A large body of air with uniform temperature and humidity.
-
A small body of air with uniform temperature and humidity.
-
A body of air with varying temperature and humidity.
-
A body of air with varying temperature and uniform humidity.
A
Correct answer
Explanation
An air mass is a large body of air with uniform temperature and humidity that covers a large area of the Earth's surface.
-
A boundary between two air masses with different temperatures and densities.
-
A boundary between two air masses with different temperatures and humidities.
-
A boundary between two air masses with different densities and humidities.
-
A boundary between two air masses with different temperatures, densities, and humidities.
A
Correct answer
Explanation
A front is a boundary between two air masses with different temperatures and densities.
What is the term used to describe the upward movement of air in the atmosphere?
-
Updraft
-
Downdraft
-
Convergence
-
Divergence
A
Correct answer
Explanation
An updraft is a vertical current of air that moves upward in the atmosphere, often associated with thunderstorms and other weather phenomena.
What is the term used to describe the process by which water vapor in the atmosphere condenses into liquid water droplets, forming clouds?
-
Evapotranspiration
-
Condensation
-
Precipitation
-
Transpiration
B
Correct answer
Explanation
Condensation is the process by which water vapor in the atmosphere condenses into liquid water droplets, forming clouds.
Which meteorological parameter is crucial for air quality forecasting?
-
Temperature
-
Wind speed
-
Relative humidity
-
Solar radiation
B
Correct answer
Explanation
Wind speed is a critical meteorological parameter for air quality forecasting as it influences the transport and dispersion of pollutants in the atmosphere.
Which of the following is NOT a consequence of reduced water vapor in the atmosphere?
-
Increased cloud formation
-
Increased precipitation
-
Increased drought
-
Increased humidity
D
Correct answer
Explanation
Reduced water vapor in the atmosphere leads to decreased cloud formation, decreased precipitation, and increased drought. It does not lead to increased humidity.
What is the effect of atmospheric pressure on tides?
-
It causes tides to be higher.
-
It causes tides to be lower.
-
It has no effect on tides.
-
It causes tides to be more frequent.
Correct answer
Explanation
Changes in atmospheric pressure can cause the sea level to rise or fall, resulting in higher or lower tides.
What is the average concentration of water vapor in the Earth's atmosphere?
A
Correct answer
Explanation
The average concentration of water vapor in the Earth's atmosphere is approximately 1%.
What is the role of the ABL in the formation of clouds?
-
It provides moisture for cloud formation.
-
It provides lift for cloud formation.
-
It provides condensation nuclei for cloud formation.
-
All of the above
D
Correct answer
Explanation
The ABL plays a crucial role in the formation of clouds by providing moisture, lift, and condensation nuclei.
How does the ABL influence the transfer of heat and moisture between the Earth's surface and the atmosphere?
-
It facilitates the exchange of heat and moisture through convection.
-
It acts as a barrier to the exchange of heat and moisture.
-
It has no significant influence on the exchange of heat and moisture.
-
None of the above
A
Correct answer
Explanation
The ABL plays a crucial role in facilitating the exchange of heat and moisture between the Earth's surface and the atmosphere through convection.
