What meteorological phenomenon is characterized by the transition of air into a cooler state resulting in condensation?

1. Precipitation

2. Wind shear

3. Cooling

4. Convection

The correct answer is: Cooling

The phenomenon characterized by the transition of air into a cooler state resulting in condensation is cooling. When air cools, particularly at night or when it rises and expands, its ability to hold moisture decreases. This leads to saturation, and when the air reaches its dew point, condensation occurs, forming clouds or precipitation. This process is fundamental in meteorology as it influences weather patterns and the formation of various types of weather events. In contrast, precipitation refers specifically to the water that falls from the atmosphere to the ground, which can occur as rain, snow, sleet, or hail, but it is not the process of cooling itself. Wind shear relates to the change in wind speed or direction with altitude, affecting aircraft performance but not directly tied to condensation. Convection involves the vertical movement of air caused by differences in temperature and density, often leading to rising warm air and cooler air descending, but cooling specifically focuses on the temperature drop that leads to condensation.
