The boundary between two air masses is called a weather front.

Here, wind, temperature, and humidity change abruptly, producing atmospheric instability.

Differential warming, as a result, causes changes in the temperature and weight of overlying air masses.

As an air mass warms, it becomes lighter and rises higher into the atmosphere.

Fast-moving, upper atmosphere winds known as jet streams help move weather systems around the world.

Large weather systems called cyclones rotate counter-clockwise in the Northern Hemisphere (clockwise in the Southern Hemisphere); they are also called “lows,” because their centres are low-pressure areas.This essay aims to help understand such divergent predictions by clarifying the concepts of weather and climate.First, the widely-read panel fixed effects models capture only the impacts of weather fluctuations but not of climate normals.Even the degree of urban development, which creates “heat islands,” and the amount of snow cover, which chills an overlying air mass, play important roles.The next time you watch a weather report on television, think about the many factors that influence our weather, some thousands of miles away, that help make the weather what it is.As an air mass cools, it becomes heavier and sinks.Pressure differences between masses of air generate winds, which tend to blow from high-pressure areas to areas of low pressure.Early one morning when it was still dark, I woke up suddenly.
