Hint: The atmospheric temperature is seen showing the variance under the effect of humidity and the atmospheric pressure. And this variance in the atmospheric temperature is known as Dew point. Water droplets get condensed below this temperature.
Complete step by step answer:
As we know that the Dew point is the temperature which allows the atmosphere to hold moisture under the effect of humidity and atmospheric pressure. Below which the water droplets get condensed leading to the maximization of relative humidity and finally the Dew point becomes equal to the room temperature.
Now let us look at its mathematical approach and formula:
${T_d} = T - \dfrac{{100 - RH}}{5}$
(${T_d}$ = dew point temperature, $T$ = room/observed temperature, RH= relative humidity)
When it rains, the relative humidity gets closer to $100\% $ which results ${T_d}$ to be equal to $T$
Note: Another term pops out for the phenomenon of temperature getting lower than the melting point of water and this point is called the frost point. At dew point, the air cannot hold more water in gaseous form and hence gets condensed.
