heats up thermal dome grows warm air starts rise cold air rushes take its place cold replacement air effect call sink altitude 30 40 feet prevailing wind has noticeable effect wind will start pushing top over Slowly top thermal grows lopsided bubble colder air replacing warm air denser thus causes base thermal shrink Sooner later base shrinks down nothing bubble free process causes thermal pop

heats up thermal dome grows warm air starts rise cold air rushes take its place cold replacement air effect call sink altitude 30 40 feet prevailing wind has noticeable effect wind will start pushing top over Slowly top thermal grows lopsided bubble colder air replacing warm air denser thus causes base thermal shrink Sooner later base shrinks down nothing bubble free process causes thermal pop
