World, 2025: annual mean maximum temperature and annual precipitation. The interactive map<\/a> has the full legend and every year from 1950 to 2025.<\/em><\/p>\n

I adapted Milan Janosov’s bivariate climate map<\/a> into an interactive map<\/a> for Europe, the other continents and World. It shows annual temperature and precipitation together with a 4\u00d74 color palette. Janosov’s tutorial builds on earlier work by Muhammad Mohsin Raza<\/a> and Fil \/ Philippe Rivi\u00e8re<\/a>. And both are fantastic, very inspirational.<\/p>\n

The data comes from TerraClimate v1.1<\/a> for every year from 1950 to 2025. Temperature is the mean of the twelve monthly maximum temperatures; precipitation is the annual total. Each region’s thresholds stay fixed across the years, so a color means the same ranges in 1950 and in 2025. Thresholds differ between regions, and the World view puts all continents on one scale.<\/p>\n

You can play through the years, inspect a city or a point on the map, turn smoothing off and download the current frame as a PNG.<\/p>\n

One detail in Antarctica is unresolved: a straight color boundary runs out from the South Pole. It appears in both the interactive map and the notebook output, and I haven’t found its cause.<\/p>\n

The code is on GitHub<\/a>. The step-by-step notebook<\/a> downloads TerraClimate’s monthly files, calculates the annual values and draws one year’s map for each of the eight views.<\/p>\n","protected":false},"excerpt":{"rendered":"
