This image was captured at 7am on Thursday, May 14. The lines show wind direction at the surface, indicating the importance of flows toward and away from coastlines. The colors indicate temperature and show the importance of continentality. At this early hour of the day, land masses remain cooler than the oceans, and high elevations are cooler than low.
This image is from a project known as Natural Earth, an artistic rendering of winds or currents overlaid on data about speed, temperature, or pressure. From the very simple main page, click on the word "earth" for a menu of options that include mapping high-altitude winds or shifting backward or forward in time.
