Horizontal pressure gradient forces are generated within thermal circulations because: o cold air rises and warm air sinks. o aloft, high pressure develops in cold air regions while low pressure develops in warm air regions o at the surface, high pressure develops in warm air regions while low pressure develops in cold air regions o in cold regions, isobars bunch closer together, while in warm regions, they spread farther apart
