China's national observatory on Monday issued a yellow alert for sandstorms in the northern part of the country. “    1    （start）from Monday to 8 a. m. Tuesday, affected by cold fronts and heavy winds, floating sand and dust       2    （expect）to sweep parts of several northern provinces and the city of Beijing,”     3    （forecast）the NMC.

Some regions in Inner Mongolia, Ningxia, Shaanxi and Shanxi were hit by strong sandstorms. The capital Beijing was enveloped in yellow dust     4     Monday morning with visibility at less than 1 km,     5     followed an official yellow warning for the sandstorm. The sandstorm is the strongest and the most sweeping     6     in nearly a decade. Remote sensing images of dust in northern China show the dust from Mongolia     7    （gradual）traveled south with the airflow.

This wave of sandstorms is a result of the combined       8    （effect）of cold air and cyclones from Mongolia. “The combined action of the Mongolian cyclone and the cold high     9    （press）provided a strong impetus（动力）for the sandstorm,” said Zhang Bihui,     10     senior engineer with the NMC.

3 . Much of the United States is locked by an unusually large winter storm, which has sent temperatures dropping sharply across the country, from coast to coast and as far south as southern Texas. In many areas, ice and snow storms have added to the challenges. Only a few areas in the south have dodged the freezing weather pattern. The National Weather Service( NWS) says that a winter storm, this large and this serious, has almost never been seen before.

The NWS reports that over 150 million Americans were under winter storm warnings. In Texas, over 2.7 million people were left without power on Monday. Texas isn't used to such serious winter weather. In the city of Houston, temperatures have dropped to - 9℃. The storm has led to huge, deadly highway accidents, and has forced its airport to cancel flights. On Sunday, President Joe Biden declared an emergency in Texas, allowing the state to get more help for the weather disaster from the US government. Several other states have declared some sort of weather-related emergency. In Washington and Oregon, warming shelters were opened to help people stay warm and safe.

The NWS says cold air from the Arctic is behind the record-breaking low temperatures. Though it may seem surprising, global warming may be one of the causes. A strong wind known as the jet stream usually flows in a circle around the Arctic, keeping super-cold air near the North Pole. But as the jet stream weakens because of climate change, the cold air is able to escape the Arctic and bring freezing temperatures to places that are normally much warmer.

The NWS is forecasting there’ll be more snow and freezing rain over the next few days as a new storm cuts up toward the Northeast from the middle of the country. The NWS says that much of the country will continue to have extremely cold temperatures, and it's likely that hundreds of cold weather records will be broken. Perhaps, people should think about the consequences of global warming.
