When you have heavy rain for a short period of time that causes flooding, we call this 'flash flooding', because it can happen in a flash! NettetThe Earth's atmosphere exerts pressure on the surface. Pressure is measured in hectoPascals (hPa), also called millibars. Standard pressure at sea level is defined as 1013hPa, but we can see large areas of either high or low pressure. These areas are all relative to each other, so what defines a high will change depending on the area around it.

NettetStatic stability is defined as the stability of the atmosphere in hydrostatic equilibrium with respect to vertical displacements. These displacements are explained by using the parcel method. The parcel is a hypothetical box that does not allow any transfer of heat into or out of the box, but allows only adiabatic temperature changes.
