Q1Consider the following statements about the Köppen climate classification: 1. It uses temperature, precipitation and seasonality. 2. Groups A, C, D and E are humid groups, while Group B is dry. 3. Its climate classes form permanent natural boundaries that cannot shift with datasets or climate change. Select the correct answer using the code given below.
Statements 1 and 2 are correct. Köppen classification uses temperature, precipitation and seasonality; A, C, D and E are humid groups, while B is dry. Statement 3 is incorrect because these are empirical categories whose boundaries can shift with datasets and climate change.
Q2Match List I with List II: List I (precipitation mechanism) 1. Convectional 2. Orographic 3. Frontal 4. Cyclonic List II (associated process) a. Low-pressure convergence b. Mountain barrier c. Hot-surface uplift d. Contrasting air masses Select the correct answer using the code given below.
Option B is correct. Convectional precipitation follows hot-surface uplift, orographic precipitation a mountain barrier, frontal precipitation contrasting air masses, and cyclonic precipitation low-pressure convergence.
Q3Consider the following statements comparing tropical and temperate cyclones: 1. Tropical cyclones are warm-core and non-frontal systems. 2. Temperate cyclones draw energy mainly from horizontal temperature contrasts with upper-air support. 3. Temperate cyclones generally move from west to east with the westerlies. Select the correct answer using the code given below.
All three statements are correct. Tropical cyclones are warm-core lows without fronts. Temperate cyclones are frontal, baroclinic systems powered by horizontal temperature contrast and upper-air support, and they generally travel west to east with the westerlies.
Q4Consider the following statements about air masses: 1. The maritime or continental label identifies the moisture source of an air mass. 2. The tropical or polar label identifies its thermal origin. Which of the statements given above is/are correct? Select the correct answer using the code given below.
Both statements are correct. Maritime and continental classify an air mass by moisture source, whereas tropical and polar classify it by thermal origin. Thus maritime air is not automatically warm, and continental air is not automatically cold.
Q5Match List I with List II: List I (form) 1. Dew 2. Frost 3. Fog 4. Hail List II (formation condition) a. A cloud near the ground, common during calm, moist and stable winter nights b. Formation on cooled surfaces when temperature remains above freezing c. Formation by deposition below freezing d. Growth in strong cumulonimbus clouds through repeated passage of ice pellets in supercooled water Select the correct answer using the code given below.
Option C is correct. Dew forms on cooled surfaces above freezing, frost forms by deposition below freezing, fog is a cloud near the ground common on calm, moist and stable winter nights, and hail grows in strong cumulonimbus clouds as updrafts repeatedly carry ice pellets through supercooled water.

6Arrange the following stages of the warm-cloud coalescence process from the earliest to the formation of precipitation: 1. Larger droplets collide with smaller droplets. 2. Larger droplets fall faster than smaller droplets. 3. Droplets grow through coalescence. 4. Droplets become large enough to overcome updrafts. Select the correct answer using the code given below.
7Consider the following statements about atmospheric humidity: 1. Absolute humidity expresses actual water vapour per unit volume of air. 2. Relative humidity can rise when air temperature falls even if no new moisture is added. 3. A high dew point indicates genuinely moist air. Select the correct answer using the code given below.
8Consider the following statements about precipitation within clouds: 1. In cold clouds, ice crystals grow at the expense of supercooled droplets because saturation vapour pressure over ice is lower than over water. 2. In warm tropical clouds, larger droplets fall more slowly than smaller droplets and therefore cannot grow by collision. Which of the statements given above is/are correct? Select the correct answer using the code given below.
