How much rain does China get?

You might as well ask how much precipitation the earth gets, because it's nearly the same range. Parts of the Gobi Desert average less than an inch of precipitation, while parts in the southeast and in Himalayan Valleys impacted by the monsoon receive well over 100 inches. In general, there's quite a lot of precipitation near the ocean in the southeast and east, and very little as you go west, especially over the Tibetan Plateau and obviously the Gobi Desert.

Worst thunderstorm in the world?

•On May 31, 1889, after days of rain, the South Fork Dam collapsed and unleashed 20 million tons of water from its reservoir. A wall of water, reaching up to 70 feet high, swept 14 miles down the Little Conemaugh River Valley, carrying away steel mills, houses, livestock and people. At 4:07 p.m., the floodwaters rushed into the industrial city of Johnstown, crushing houses and downtown businesses in a whirlpool that lasted 10 minutes (

What does a weather vane do and how does it work?

A wind vane has a horizontal bar (sometimes it's a tube or shaft), which is mounted upon a circular pivot point that allows the bar to freely spin around in a horizontal plane pointing in any direction of the wind. A tail is placed at one end of the bar and the other end is used as the direction indicator (the pointer). The tail has more wind resistance than the small pointer, so a wind will always force the tail. This points the indicator (the pointer) into the wind to correctly show the wind direction. Often this pivot point is placed just slightly close toward the point than the tail. This adds leverages to the mechanical energy of the wind force placed upon the tail, which allows the indicator to correctly point into the wind even with low wind speeds. A windsock, often seen at airports or near helicopter pads points the opposite way of a weather vane - a windsock points into the direction where the wind is going, not from where it came like the wind vane.The wind vane rotates freely on a veritical rod and becomes aligned by the direction of the wind.
