with the flow shifting from north and south. “It’s the difference between the really warm air at the equator and the cold air at the pole that keeps the jet streams in line as they whip around the planet,” he says. The bigger the temperature difference in the air, the better the balance at keeping the jet stream. During the winter when the temperature gap is at an all-time high, jet streams travel with strong and fast cold winds to the south.
Heat waves on land could also be a potential culprit. Zaitchik explains that as warm air rises, it creates a low-pressure system over regions like in Pakistan, which already experience hot and dry temperatures. The low pressure sucks the air coming in and removes moisture from the ocean., a hydrologist and environmental science professor at Barnard College, says that the world is currently in a La Niña period that tends to make Pakistan and other Asian countries wetter in the summer.
