The inversion boundary varies its altitude primarily in response to the weight of the air above it, which is measured in terms of atmospheric pressure.

View moreStorms are created when a center of low pressure develops with the system of high pressure surrounding it.
View moreSmall localized areas of low pressure can form from hot air rising off hot ground, resulting in smaller disturbances such as dust devils and whirlwinds.
