We Will Never Be Able To Perfectly Predict The Weather

Would you rather hear these stories in less than 10 minutes? Listen to our brand new daily podcast here.

It may seem like modern technology and meteorology should have a firm grip on future weather, but in reality, weather has too many variables to ever be fully predictable. Small changes in air currents, pressure, and heat can cause events to take surprising turns. But, even though chaos theory prevents us from becoming storm psychics, we can try to use our knowledge of it to develop more accurate prediction methods. For example, meteorologists now create ensemble forecasts, which are groups of several potential forecasts based on slight differences in factors at the start of each.
