Today's Weather Forecast-Sunny in the Deserts, Rainy in the Rainforests

I was looking something up on CNN when I came across these weather maps. What's remarkable (or not) is how well they seem to conform to the climate zone patterns of the world. I poorly stitched together the southern hemisphere continents minus Australia (too hard to deal with the scale difference there). I had to rotate Asia for projection issues. Anyway here's a comparison.
