Consider the following statements:

1. In deserts, rain normally occurs as violent thunderstorms of the convectional type.
2. In deserts, there is high diurnal range of temperature.

Which of the following statements is/are correct?

Convectional rainfall occurs when the energy of the sun (or insulation) heats the earth’s surface and causes water to evaporate, finally changing to water vapour. This warm, moist air then rises, and as it rises it cools. The air reaches a point called the condensation level where it has cooled to such an extent that the water vapour condenses and turns back to a liquid form. This process of condensation high in the atmosphere leads to the development of clouds. As the clouds continue to grow the weight of the water droplets can eventually lead to precipitation. Deserts experience convectional type of rainfall. In deserts, the diurnal range of the temperature is very high. They receive high insolation during the day time in absence of cloud cover, and reflect back this heat during night.
