    Characteristics of Cold Air Masses
    - Low specific humidity is a characteristic of cold air masses

    Conditions for Precipitation
    - Precipitation occurs when there is enough moisture in the air to form clouds, and when the clouds become saturated and cannot hold any more moisture
    - Precipitation can occur in a variety of conditions, including when a cold air mass lies over a warm ocean surface, but it is not the only condition for precipitation

    Origination of Warm Air Masses
    - Warm air masses generally originate in the subtropical regions, which are areas closer to the equator where temperatures are warmer and there is more moisture in the air

    Correct Statements
    - Statement 1 is correct, as low specific humidity is a characteristic of cold air masses
    - Statement 2 is partially correct, as precipitation can occur in a variety of conditions and not just when a cold air mass lies over a warm ocean surface, but this condition can contribute to precipitation
    - Statement 3 is correct, as warm air masses generally originate in subtropical regions

    Overall, all three statements are correct, making option D the correct answer.

    • Cold air masses: Cold air masses originate in the polar and arctic regions. They are characterized by the following properties in their source regions:
      • Specific humidity is extremely low. Hence statement 1 is correct.
      • Stability increases and normal lapse rate of temperature is low.
    • Cold air masses after moving from their source regions and reaching other areas have the following properties:
      • Temperature of that areas where cold air masses reach starts decreasing.
      • The air mass is warmed from below and thus normal lapse rate increases and the air becomes unstable. This mechanism causes convective currents.
      • If the cold air mass lies over warm ocean surface, then its specific humidity increases and cumulo- nimbus clouds are formed.
    • Precipitation occurs only when the cold air mass lies over warm ocean surface but if it lies over warm continent, there is clear weather. Hence statement 2 is correct.
    • If the cold air mass lies partly over warm ocean surface and partly over the adjoining cold land surface, then cyclonic conditions are induced.
    • Warm air mass: Warm air mass is that whose temperature is greater than the surface temperature of the areas over which it moves.
    • Warm air masses generally originate in the subtropical regions characterized by anticyclonic conditions. Hence, statement 3 is the correct.
