Question 1

Within the Hadley cell, the air that rises near the equator moves poleward at high altitudes. At what approximate latitude does this air sink to create the subtropical high-pressure belt, and what is its thermodynamic characteristic?

Between 30° and 35° latitude, sinking adiabatically and warming to create dry, stable air masses. At approximately 60° latitude, cooling radiatively to form the polar front. Between 10° and 15° latitude, warming adiabatically to produce intense convective cloud bands. At the geographical poles, sinking and cooling to maintain the polar high-pressure cells.

Correct Answer:

Between 30° and 35° latitude, sinking adiabatically and warming to create dry, stable air masses.

Question 2

During the transition periods between the Southwest and Northeast monsoons (inter-monsoon periods) in Sri Lanka, what is the primary meteorological feature causing widespread afternoon thunderstorms?

The passage of the Intertropical Convergence Zone (ITCZ) directly over the island, combined with strong diurnal insolation and sea breeze convergence. The development of strong mid-tropospheric westerly jet streams that trigger mountain wave turbulence. The presence of a persistent Siberian high-pressure system that pushes dry cold fronts across the Indian Ocean. The cooling of the sea surface temperature surrounding Sri Lanka below 20 degrees Celsius, initiating coastal radiation fog.

Correct Answer:

The passage of the Intertropical Convergence Zone (ITCZ) directly over the island, combined with strong diurnal insolation and sea breeze convergence.

Question 3

What are the typical wind direction and atmospheric conditions observed over Sri Lanka during the Southwest Monsoon, which runs from June to September?

Southwesterly surface winds, bringing heavy orographic precipitation to the windward (southwestern) slopes of the central hills, while the leeward (northeastern) areas experience dry Foehn-like conditions. Northeasterly surface winds, bringing dry continental air from the Indian subcontinent across the entire island. Variable light winds with severe morning radiation fog over coastal aerodromes like Colombo (VCBI). Strong southeasterly trade winds carrying sub-freezing air masses and severe snow showers to altitudes above 3,000 feet.

Correct Answer:

Question 4

The Northeast Monsoon in Sri Lanka, occurring from December to February, is characterized by which of the following atmospheric patterns?

Northeasterly winds carrying moisture from the Bay of Bengal, producing rain over the northern and eastern parts of the island. Dry, stable air sinking from the upper troposphere, completely suppressing all cloud formation across the island. Strong westerly winds causing severe dust storms over the Jaffna Peninsula. Widespread snow accumulation on the peaks of the central highlands due to the intrusion of subpolar air.

Correct Answer:

Northeasterly winds carrying moisture from the Bay of Bengal, producing rain over the northern and eastern parts of the island.

Question 5

Why are the inter-monsoonal months of October and November in Sri Lanka particularly prone to frequent and widespread flooding?

The ITCZ is positioned over the island, and the lack of strong prevailing winds permits intense local convective development, often enhanced by low-pressure systems or depressions in the Bay of Bengal. A continuous flow of dry continental air from Tibet causes rapid evaporation and subsequent massive condensation cycles. The presence of the subtropical jet stream directly over the central hills, causing massive mechanical lifting of air. Frequent volcanic activity in the Indian Ocean releasing condensation nuclei that trigger continuous non-convective rain.
