How Reliable Are Weather Forecasts?

 

 

Dataset and key variables

The dataset Weather_forecast_Accuracy includes 16 months of forecasts and observations from 167 cities.

1. weather_forecasts:

   • Date, City and State, Observed Temp and Forecast Temp

2. cities:

   • longitude, latitude, Cities, Temperature forecasting errors

3. outlook_meanings:

   • Forecast_outlook, meaning

Question 1: How does the error in temperature prediction vary across the United States? Can we identify clusters of cities with similar error patterns?

Visualize the mean temperature prediction error by city

Identifyng error per cluster on a map

Question 2: Geographic Seasonality in Temperature Forecasting Errors

Do seasons impact Weather forecasting ?

Winter

Spring

Summer

Fall
