Drought occurs due to deep underground fires. Methane hydrate there is ignited from various fires. Watering large trees a bit violently extinguishes deep fires.
Heavy rains, hurricanes, tornadoes etc. occur when there is too much water vapor in the sky. The greater the amount of water vapor, the larger the scale. Water vapor is invisible, but clouds are visible. We can guess the movement of the water vapor through the movement of clouds.
