Weather affects all of us in one way or another, directly or indirectly. For example, good weather makes people happy. Bad weather makes people sick and depressed. Be sides, on a fine day, one can go out for a walk or play a game in the open. On a rainy day, however, he can only stay indoors, in a word, weather is part of life for all of us.
The first thing that many people do after getting up is to see what the weather is like. With a knowledge of the weather people can arrange work and life of the day. If it is fine, he may decide to go on a picnic. If it is cloudy, he will have to take a raincoat or an umbrella with him when he is leaving the house. Whatever the weather may be, one tends to adjust his activities to it accordingly.
In order to know what the weather will he, special people are hired 1o provide this information. They collect data, analyze them and predict the weather of the coming day. This information, which is announced on the radio or on TV, is usually very accurate. Thanks to the efforts of those professionals, we can always know the weather in advance and get prepared for it.

The weather of these days is really bad. It s foggy and there is haze in the air. So, we can t see the things very far. Every morning, when I pull back the curtain, I only can see the building dozens miles away.

I do as she tells. Because of the bad weather, car accidents happen more frequently. I hope drivers can drive more carefully and keep safe.

The weather is a set of all the phenomena in a given atmosphere at a given time. It also includes interactions with the hydrosphere. The term usually refers to the activity of these phenomena over short periods (hours or days), as opposed to the term climate, which refers to the average atmospheric conditions over longer periods of time. When used without qualification, "weather" is understood to be the weather of Earth.
Weather most often results from temperature differences from one place to another. On large scales, temperature differences occur because areas closer to the equator receive more energy per unit area from the Sun than do regions closer to the poles. On local scales, temperature differences can occur because different surfaces (such as oceans, forests, ice sheets, or man-made objects) have differing physical characteristics such as reflectivity, roughness, or moisture content.
Surface temperature differences in turn cause pressure differences. A hot surface heats the air above it and the air expands, lowering the air pressure. The resulting horizontal pressure gradient accelerates the air from high to low pressure, creating wind, and Earth's rotation then causes curvature of the flow via the Coriolis effect. The simple systems thus formed can then display emergent behaviour to produce more complex systems and thus other weather phenomena. Large scale examples include the Hadley cell while a smaller scale example would be coastal breezes.
The strong temperature contrast between polar and tropical air gives rise to the jet stream. Most weather systems in the mid-latitudes are caused by instabilities of the jet stream flow (see baroclinity). Weather systems in the tropics are caused by different processes, such as monsoons or organized thunderstorm systems.
Because the Earth's axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. In June the Northern Hemisphere is tilted towards the sun, so at any given Northern Hemisphere latitude sunlight falls more directly on that spot than in December (see Effect of sun angle on climate). This effect causes seasons. Over thousands to hundreds of thousands of years, changes in Earth's orbital parameters affect the amount and distribution of solar energy received by the Earth and influence long-term climate (see Milankovitch cycles).
On Earth, common weather phenomena include such things as wind, cloud, rain, snow, fog and dust storms. Less common events include natural disasters such as tornadoes, hurricanes and ice storms. Almost all familiar weather phenomena occur in the troposphere (the lower part of the atmosphere). Weather does occur in the stratosphere and can affect weather lower down in the troposphere, but the exact mechanisms are poorly understood.[1]
The atmosphere is a chaotic system, so small changes to one part of the system can grow to have large effects on the system as a whole. This makes it difficult to accurately predict weather more than a few days in advance, though weather forecasters are continually working to extend this limit through the scientific study of weather, meteorology. It is theoretically impossible to make useful day-to-day predictions more than about two weeks ahead, imposing an upper limit to potential for improved prediction skill.[1] Chaos theory says that the slightest variation in the motion of the ground can grow with time. This idea is sometimes called the butterfly effect, from the idea that the motions caused by the flapping wings of a butterfly eventually could produce marked changes in the state of the atmosphere. Because of this sensitivity to small changes it will never be possible to make perfect forecasts, although there still is much potential for improvement.
The sun and oceans can also affect the weather of land. If the sun heats up ocean waters for a period of time, water can evaporate. Once evaporated into the air, the moisture can spread throughout nearby land, thus making it cooler.

The world meteorological day is a day, the world meteorological organization on March 23, time of the year. Of "the world meteorological day" every year to determine a theme, requires each member celebrations on this day, and the extensive publicity of the important role of meteorological work.
Former World Meteorological Organization that unofficial international Meteorological agency cooperation, in its member countries on behalf of the World Meteorological Organization treaty signed a year, from the date of March 23, 1951, was reorganized as the World Meteorological Organization (World Meteorological Organization, WMO), become the international climate cooperation between government agencies, and establish the relations with the United Nations.
In 1960, the world meteorological organization executive committee decided to take a year on March 23, as world day, requires each member celebrations on this day each year, and the extensive publicity of the important role of meteorological work.
World meteorological day every year have a central content, each member in this day according to the center of the content, carry out various forms of propaganda and commemorative activities, organize the masses to visit our meteorological offices and stations, to hold a government leaders to attend the celebration of the masses, organize meteorological instrument and equipment, pictures, charts, and data display, held a press conference, by the newspapers, radio stations and television stations reported feature articles and speeches, meteorological science films, commemorative stamps and so on
