Final answer:
Predicted windshear (PWS) is not exclusively depicted in clear air or cloudy conditions, nor is it exclusive to nighttime. PWS is a tool used by meteorologists to assess the rotation in the atmosphere for tornado prediction.
Step-by-step explanation:
Predicted windshear (PWS) is not specifically depicted in clear air or cloudy conditions, nor is it exclusive to nighttime. PWS is a change in wind speed or direction over a short distance and can occur in different weather conditions. It is a tool used by meteorologists, such as in tornado prediction, to assess the rotation in the atmosphere that can lead to tornado formation. Conditions with greater rotation are more likely to produce tornadoes.
