Squalls

According to its destructive power barrage not only not inferior to the storms, but often exceeds them. In 1978 there was a terrible accident with the British military frigate Eurydice. The ship was returning from a long voyage. On the pier he was waiting for the crowd welcoming. Finally the frigate appeared on the horizon. It was a high-speed craft, and he was fast approaching, with every minute looming clearer and clearer. And so to the coast there are not more than two kilometers. Suddenly flew heavy wind. People on shore were knocked down and covered with wet snow. Huge masses of snow shut down the entire horizon and turned day into night. At sea, the wind picked up huge mounds. But it did not last long. Five minutes later the storm wind suddenly died down, stops pouring snow, the sky quickly cleared. Frigate on the horizon was not. He was overthrown a strong blow of wind, and instantly sank with all hands. He was found a few days later, on the seabed near the entrance to the bay. After the disaster at the squalls have paid close attention to academics. From different places quickly gathered information about the hurricane, which roared past the bay, where the sinking of "Eurydice." As it turned out, a hurricane raced at a speed of 90 kilometers per hour and was very narrow, only 2-3 km strip. This band reaches a length of 700 kilometers. After some time, scientists have found the cause of such a strong and sudden wind of the incident. Flurry usually occurs during the invasion of cold air flow into the broad masses of warm. Cold air is rapidly replacing the warm and makes him go up. At the top of the warm air cools and forms a cumulonimbus cloud. Of these clouds and descend a flurry of rain, snow or hail. In front of the wind is blowing slightly. But the wind is blowing along the front, as he quickly picks up speed and is carried by a long narrow strip. This band has a width of 500 to 6000 meters. A hail cloud can learn from afar. It is usually black. It clouds ragged edges. These edge like claws descend. Inside the cloud is visible white curtain of rain. A hail cloud is low over the ground. The bottom edge of its constantly changing form. In 1942, the American city Takama strong squall tore kilometer bridge that hung over the bay. In our century, scientists already know how to calculate path squall. For this purpose, are made daily weather maps. Tracing the promotion of a cold front, we can promptly notify the areas that might descend squall.
