Is it theoretically possible? What would it look like? Temperatures in India would fall by how much? Is it economical in the super long term? Impact on globe net positive or negative? Runaway global warming leads to planet heat death? Completely unrelated, how does the rain thing work lol its so confusing what causes rain in certain areas and not others lol...?
Thank you for reading this long ass post (-:
Suppose a high pressure cell does set up over the Tibetan Plateau, raising the air temperature to a very pleasant 21 °C at the collection point. That air will be a deadly 60 °C by the time it descends on New Delhi, and the relative humidity will be in the low single digits. This is a deadly combination.
A similar phenomenon called the Santa Ana winds happens every year in southern California. Natural channels in the Sierra Nevada and the coastal mountains allow air to flow from the US southwest's high desert toward the southern California coast when conditions are right. The adiabatic heating makes autumn the time of the year when the highest temperatures are recorded near the souther California coast.
