a forecast indicates a dew point temperature equal to the air temperature. What does this information imply?
a relative humidity is 0%, and it may rain
b relative humidity is 100%, and it may rain
c relative humidity is 0%, and there is no chance of rain
d relative humidity is 100%, and there is no chance of rain
The correct answer is:
b) relative humidity is 100%, and it may rain.
When the dew point temperature is equal to the air temperature, it means that the air is saturated with moisture. This results in a relative humidity of 100%. Since the air is already saturated, there is a high chance that the moisture will condense and form precipitation, which in this case, may be rain.
