The Doppler Effect is super important for predicting the weather. It helps make forecasts about rain and storms more accurate using radar technology.

Meteorologists, who are the weather experts, use Doppler radar to see how raindrops and storms are moving.

Here are some key ways they use it:

1. Measuring Speed: Doppler radar can check how fast rain is falling, with speeds usually between 0 and 100 miles per hour.

2. Tracking Storms: By looking at changes in sound waves, meteorologists can find out which way storms are moving and how fast. This can help them warn about tornadoes up to 13 minutes in advance!

3. Estimating Rainfall: Doppler radar can also guess how much it’s going to rain, getting it right about 90% of the time.

Some quick facts:

• About 90% of storms can be tracked well using Doppler radar.
• The National Weather Service has around 159 Doppler radar units across the U.S. to gather information in real time.
