A storm (from Proto-Germanic *sturmaz "noise, tumult") is any disturbed state of an astronomical body's atmosphere, especially affecting its surface, and strongly implying severe weather. It may be marked by strong wind, hail, thunder and/or lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain (ice storm), strong winds (tropical storm, hurricane, windstorm) or wind transporting some substance through the atmosphere (as in a dust storm, blizzard, sandstorm, etc.).

Storms generally lead to negative impacts to lives and property, such as storm surge, heavy rain or snow (causing flooding or road impassibility), lightning, wildfires, and vertical wind shear which can cause airplane crashes. However, systems with significant rainfall can alleviate drought in places they move through. Heavy snowfall can allow special recreational activities to take place which would not be possible otherwise, such as skiing and snowmobiling.

A teacup is a small cup, with or without a handle, generally a small one that may be grasped with the thumb and one or two fingers. It is typically made of a ceramic material. It is usually part of a set, composed of a cup and a matching saucer. These in turn may be part of a tea set in combination with a teapot, cream jug, covered sugar bowl and slop bowl en suite. Teacups are wider and shorter than coffee cups, but not always.

Some collectors acquire numerous one-of-a-kind cups with matching saucers. Better teacups typically are of fine white translucent porcelain and can be decorated with floral patterns. They may also memorialize a location, person, or event. Such collectors may also accumulate silver teaspoons. These usually have a decorated enamel insert in the handle with similar themes.

The first small cups specifically made for drinking the new beverage tea seen in Europe were exported from the Japanese port of Imari. Tea bowls in the Far East did not have handles, and the first European imitations, made at Meissen, were without handles, too. Countries in East Africa like Eritrea also use the handeless cups to drink boon which is traditional coffe there.

Chinese teacups are very small, normally can hold no more than 30ml of liquid. They are designed to be used with Yixing teapots or Gaiwan.
