Insights from NOAA’s public area database

A map of the contiguous United States showing tornado touchdown locations as red dots. State and county boundaries are outlined in blue and light gray, providing geographic context. The red dots are scattered unevenly, with higher concentrations in areas known as Tornado Alley, including parts of Texas, Oklahoma, Kansas, and Nebraska.

When you’re concerned with finding out tornadoes, the Nationwide Oceanic and Atmospheric Administration (NOAA) has a beautiful public-domain database to make your day. Extending again to 1950, it covers twister beginning and ending areas, magnitudes, accidents, fatalities, monetary prices, and extra.

The info is accessible via NOAA’s Storm Prediction Heart. Along with the uncooked information, this website provides many charts and maps that slice and cube the info in a number of methods. One in all my favourite maps is the 20-year common of extreme climate watches. It makes it appear to be Oklahoma’s borders are largely primarily based on unhealthy climate!

A colorful map of the contiguous United States shows counties colored by annual severe weather watches. The largest number of watches is colored yellow; the minimum number is white to light blue. State and county boundaries are outlined in black and light gray, providing geographic context. The yellow counties are concentrated in Oklahoma and seem to follow its state boundary.

These prefab maps are helpful, however they’ll’t deal with each scenario. There will likely be occasions when it is advisable make customized maps, both to reply a selected query or to include exterior information.

On this Fast Success Information Science challenge, we’ll use Python, pygris, GeoPandas, Plotly Categorical, and a part of NOAA’s in depth database to map twister occurrences, graph their…
