Instability forms from daytime heating of the earth’s surface heating the air around it causing it to rise because warm air is lighter than cool air, this is called the updraft. When … Continue reading »

What is Adiabatic Cooling?

“What is adiabatic cooling and how does it impact the weather in our region?” Gary Jones Medford There are two types of adiabatic cooling: dry and wet. Dry adiabatic cooling is when a rising air parcel is not saturated and it cools as it rises at 10C/1km or as it sinks it warms at the … Continue reading »
