The Challenge of Weather Forecasting
Learning Objective
I can describe how difficult it is to forecast weather.
Key Concepts
About 40% of rain comes from large air masses called fronts, which are relatively easy for meteorologists to track and predict.
The majority of rain comes from convection, which is triggered by heat from the ground warming up a small mass of air.
Convective rain is hard to predict because it depends on many variables, such as how warm the ground is, how much water vapor the air holds, and how long the air stays over the warm ground.
