After an unusually warm weekend in the eastern United States, a strong winter storm brought a fierce snowstorm to mid-Atlantic, leaving several states covered with wet snow after the snowstorm — NASA's Terra satellite captured satellite images of the area after a snowstorm on January 4, 2022, in which several states were whitewashed by a clear snow band that had been raging. The maximum depth of snow in Washington, D.C., was more than 20 centimeters in this snowstorm, and even more than 35 centimeters in parts of southern Virginia and southern Maryland.
The snowstorm significantly reduced visibility in some areas, disrupted many flights, and caused accidents on some highways due to low visibility and icy roads. This strong winter storm is actually one of the manifestations of a strong cold wave - this strong cold wave began to move south from the northwest region of the United States from December 30, and then swept through most of the United States in early January, and finally poured southward cold air masses and heating masses fiercely entangled into a winter storm, creating a fierce blizzard on many places along the Atlantic coast of the United States.
In the Midwest, the cold wave also created quite a bit of chaos — on December 30, 2021, as the cold wave began to move south, high winds roared down the western and forward slopes of the Colorado Rocky Mountains, and in the northwest of denver, the state capital, gusts peaked at 185 kilometers per hour, and the winds were comparable to hurricane landfall. The winds sparked intense wildland fires in southern Boulder County, Colorado, causing more than 1,000 homes to be destroyed or damaged, the most devastating fire event ever recorded in Colorado.
On January 1, before the cold wave completely moved south, many parts of the southern and southeastern united states were quite warm, and Texas on the Gulf Coast not only generally exceeded 25 degrees, but some stations even experienced a high temperature of 37.2 degrees Celsius.
But on January 3, after the cold wave completely moved south, Texas not only almost completely broke the freezing point, but some stations experienced a low temperature of -11 degrees Celsius. Compared with before, during this New Year's Day holiday, Texas in the United States experienced a crazy temperature difference of nearly 50 degrees of "fire star", is this the Earth's climate is messing around? This is actually the product of this strong cold wave + active warm air, which also shows that although the region is near the sea, in fact, many places still have strong continental climate characteristics, of course, this is also in line with the recent period of time, the northern hemisphere through the circulation of the characteristics of the fierce.
Then some netizens have to ask: Will such a fierce cold wave spread to our country? The United States, as the upper reaches of the westerly wind belt, may indeed transmit this violent oscillation downstream, but the specific situation needs to be seen. In general, before the arrival of the Spring Festival, everyone also needs to pay more attention to weather changes and prepare in time.
