Understanding weather and climate means looking for patterns and connections.
Have you ever wondered how the weather in your area compares with weather in other regions across the United States? Are the winters cold, the summers as mild, or as windy? This interactive tool allows you to compare these and many other variables, from multiple locations, over periods of days, weeks, or months. You can also see how two variables might be related by viewing them on a scatterplot graph. The arrangement of data points on the graph will tell you whether there is a correlation between variables such as relative humidity and temperature.
With this tool, you can also ask questions about how weather has changed over time. To explore long term change, or climate, you can look at over 100 years of data from one location - for example, New York's Central Park. Since the location is the same, the Climate Graph and Analysis tools tools can reveal patterns that occur with the passage of time.
