convectional relief is formed with the formation of convectional currents. the surface of the earth is heated and the air above it aswell. the air mass expands and becomes lighter. but as the airmass rises it cools. it continues to rise till it reaches due point. condensation occurs, clouds are formed. previpitation results. cyclonic precipitation results when the leading edge of the warm air mass meets a cool air mass. the warm air mass rises above the cool air mass. it cools adiabatically. the moisture condenses, clouds are formed, precipitation results.
An Warm air mass
The leading edge of a mass of air with certain, uniform moisture and temperature characteristics is called a front. i.e. The leading edge of a relatively warm air mass is called a warm front. The leading edge of a cooler air mass is called a cold front.
warm front
A front is an edge between two or more different air masses.

"front"
It is called a "cold front. It is the leading edge of a cooler mass of air that is replacing a warmer mass of air at ground level.
The outside edge of an area is the perimeter.
it's because of the ratio of the weight of the air in the balloon to the air outside the balloon
Mine had a small rubber plug on the outside, lower edge of the unit.
