Group 1 - The core viewpoint of the article highlights the impact of a strong cold air mass bringing significant weather changes, including extreme temperature drops, strong winds, and widespread sandstorms, particularly affecting travel during the holiday season [1][3]. - This cold air mass is characterized by a typical cold high-pressure system combined with a Mongolian cyclone, creating a large pressure gradient that leads to strong winds [3]. - The strongest winds are expected today, with gusts reaching levels of 9 to 11, and the conditions are favorable for significant sand lifting due to low soil moisture in the sand source areas [3][5]. Group 2 - The sandstorm's intensity and range are noted to be the largest observed this year, which is unusual for this time of year [7]. - The sandstorm is expected to expand southward to the lower Yangtze River region, with the most severe impacts occurring today [5]. - The combination of strong winds and sand will significantly reduce visibility, posing challenges for travel and necessitating precautions for outdoor activities [7].
