Can cyclone suck in very cold air from stratosphere?

Yes, cyclones do suck in cool air from stratosphere. Air dynamics of a cyclone is complex and contains columns of rising warm moist air and columns of descending cold air. read more

The warm moist air which rises is the one which descends in the eye of the cyclone due to which the eye has a calm weather without any disturbances whereas the eye wall has intense cyclonic winds. The warms moist air which rises hardly crosses the troposphere. So, a cyclone can’t suck in very cold air from stratosphere. read more

Yes, cyclones do suck in cool air from stratosphere. Air dynamics of a cyclone is complex and contains columns of rising warm moist air and columns of descending cold air. Cyclones are low pressure systems at mean sea level, these low pressure areas pull in warm moist air and swirl to form deep convective clouds around the cyclone. read more

Later in their life cycle, extratropical cyclones occlude as cold air masses undercut the warmer air and become cold core systems. A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the subtropical jet stream. read more
