Where does the huge volume of water go after evaporation due to long hot season?
We also have to consider other factors which are wind and monsoon winds. When monsoon wind blow across the country, it will carry the water vapors with them from high air pressure areas to low air pressure areas (places that are colder). Hence, the place will have low rate of relative humidity which causes it to be difficult to be able to form clouds. Next, when the temperature is too high, water vapor particles will continue to rise upward and the intermolecular forces between them will be much more weaken and thus, the relative humidity will also be lower which contribute to drought. Even if it’s able to form clouds and rain, the replacement level is not enough and it will continue to follow vicious cycle till monsoon winds blow to Philippines from the Antarctica and than the ocean (carrying moisture now) to there.
