According to the video, what is one reason why it is difficult to accurately forecast rain?

Convective rain is triggered by heat from small patches of ground, making it hard to predict.

Explain how fronts cause rain.

When a cold front runs into a warm front, the warm front rises, cools, and condenses water vapor, causing rain.

Fronts are large and easy to track with radar systems, allowing meteorologists to predict the intensity and duration of the rain.

Heat from the ground warms up a small mass of air, which then rises and cools, causing water vapor to condense.

I can describe how difficult it is to forecast weather.

1
About 40% of rain comes from large air masses called fronts, which are relatively easy for meteorologists to track and predict.
2
The majority of rain comes from convection, which is triggered by heat from the ground warming up a small mass of air.
3
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.
