October 20, 2013 - Autumn snow across Mongolia and northern China

Autumn snow across Mongolia and northern China

The first snowfall of autumn fell across northeast China and Mongolia on October 11, 2013. According to news reports, additional snow fell on October 14, especially in northern China’s Hailar City, as temperatures plummeted to near 0° C (32°F). The snowstorm reduced visibility and caused many accidents in and around the city.

The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite passed over the region on October 14 and captured this true-color image of the fresh snowfall clinging to the ground.

Mongolia sits in the center of the image, with a broad white band crossing the center of the country. In the west, snow sits atop part of the Khangi Mountains and also dusts the southeastern slopes of the Khentii Mountains before sweeping along the Kerulen River Basin and across the border with China. Although surrounded by snow, the grayish waters of Hulun Lake, China, remain clear and unfrozen. Snow also dusts the mountain tops south and east of Lake Baikal, Russia.

Hailar City can be found east of Hulun Lake and on the banks of the Ergune River, where, in this image, the snow appears the brightest and thickest. Temperatures were forecast to drop by an additional 10°C (18°F) in the following days as the autumn chill continues.
