Answer:
Stability
Explanation:
Stability (or atmospheric conditions) describes the tendency of the air either with rise and generate storms (destabilization) or resist vertical motion (stability).
As is valid of a balloon, the best way to explain how equilibrium functions is to consider a parcel of air getting a thin , lightweight cover that helps it to stretch but prohibits the air within from interacting with the surrounding atmosphere.

When a cyclone's strongest winds do not exceed 61 kilometers (38 miles) per hour, it is called a tropical depression
Tropical cyclones are classified based on their wind speed. When the fastest sustained winds does not exceed 38 miles per hour (61 km per hour), it is called a tropical depression.
If the fastest wind is greater than 38 miles per hour (61 km per hour), it is called a tropical storm.
However, if the maximum sustained wind speed reaches 74 mile per hour (119 km per hour) it is referred to as a hurricane.
