Not all deserts are hot and sandy. A desert is classified as a desert because it receives less than 250mm of rain annually. The Gobi can actually be classified as a cold desert sometimes.
Now for the climate:
The Gobi has cold winters (-40 degrees C/-40 degrees F) and short, hot, summers (40 degrees C/104 degrees F). The Gobi gets what little rain there is in summer in short, hard, bursts, and a little bit of snow in winter, and of course the total being less than 250mm, or it wouldn't be classified as a desert.
