The diagram represents a simplified model of the incoming (solar) and outgoing (terrestrial) electromagnetic radiation of Earth’s energy budget.
Two major greenhouse gases that absorb outgoing long-wave radiation within the atmosphere are

Southeast Asia Monsoons
The Southeast Asia monsoons are seasonal shifts in the direction of regional planetary winds. These shifts are related to the movement of air pressure belts as the Sun’s vertical ray changes latitude. In the late spring, winds begin to blow from the southwest, bringing moisture from the Gulf of Thailand across Southeast Asia. Rainfall reaches a peak in July and August. This moisture is partially blocked by the Annamite Mountains, located along the border between Vietnam and Laos. Therefore, the rainfall in central Vietnam is somewhat less during these months. In September, the winds reverse direction and begin to flow from the northeast across the Gulf of Tonkin and South China Sea. This wind shift begins the season of heavy rainfall in central Vietnam that continues for months.
Heavy rains occur in Cambodia and Thailand when the moist air brought by the monsoon
