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 proce 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 st 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 proce 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.
5、文山天气海拔高度?
文山市地处云南省东南部低纬度高原,东南近北部湾,西南邻孟加拉湾,来自这两个方向的水蒸汽带来丰沛降雨。北回归线横穿市境,市境大部在北回归线以南,属中亚热带季风气候。大部地区冬无严寒,夏无酷暑,春秋长,冬夏短,四季气候宜人。整体气候通常是“一年有冷热,久雨变成秋;冬晴如春暖,惊蛰有冬寒”。年平均日照时数2028小时,年均积温6829.3℃。无霜期平均为309天,初霜出现于12月初,终霜出现于1月底,雪天平均约10年一遇,年平均气温18.4℃,全年昼夜温差11.7℃,平均相对湿度75%,常年平均降雨量1187.8毫米,全年降雨量约28亿立方米。
文山市内地形地貌属滇东南岩溶山区,地形复杂,喀斯特岩溶地貌突出,总体地势西北高、东南低,山峦连绵起伏,河谷、沟壑纵横交错。西部有薄竹山、连云山、化余山、老君山,坡度一般在25°以上。地面海拔约1250米,山峰海拔约1500余米,薄竹山海拔2991.2米,为滇东南第一高峰,该峰临空虎踞、雄峙西南。西南部那么果河和法果河交汇处最低海拔618米,与最高峰相差达2373.2米。
6、云南省的气候特点?
云南气候:亚热带季风气候、热带季风气候。
云南气候基本属于亚热带高原季风型,立体气候特点显著,类型众多、年温差小、日温差大、干湿季节分明、气温随地势高低垂直变化异常明显。
滇西北属寒带型气候,长冬无夏,春秋较短;滇东、滇中属温带型气候,四季如春,遇雨成冬;滇南、滇西南属低热河谷区,有一部分在北回归线以南,进入热带范围,长夏无冬,一雨成秋。
在一个省区内,同时具有寒、温、热(包括亚热带)三带气候,一般海拔高度每上升100米,温度平均递降0.6°C~0.7°C,有“一山分四季,十里不同天”之说,景象别具特色。
云南地处低纬度高原,地理位置特殊,地形地貌复杂。主要受南孟加拉高压气流影响形成的高原季风气候,全省大部分地区冬暖夏凉,四季如春的气候特征。
云南全省平均气温,最热(七月)月均温在19°C~22°C之间,最冷(一月)月均温在6°C~8°C以上,年温差一般只有10°C~12°C。全省降水在季节上和地域上的分配极不均匀。
7、文山全州气候对比
文山州地处云贵高原东南部。年平均气温19度,年降雨量779毫米,全年无霜期356天,日照时数2228.9小时,多为亚热带气候,冬无严寒,夏无酷暑。
雨量充沛,但分布不均。其特征为西南部多,东北和中西部较少;山地多,谷地少;夜雨多,白天少;局部性大雨、暴雨多。干湿季分明,5~10月为雨季,雨量占全年雨量的82%;11月至次年4月为干季,雨量占年雨量的18%。因此部分地区容易发生干旱或洪涝等灾害。
太阳辐射能丰富,热量资源充足。热量分配在时、空分布上的特点是:冬季气温较高,春季气温回升快,2~4月平均每月上升4℃左右,3月份气温基本稳定在15℃以上;夏季高温不强,大部地区7月均温仅21~23℃,7月后开始下降,秋季降温快,9月份均温比7月份下降2℃以上,部分县平均最低气温已降至16℃以下。但受低云和雾雨影响,太阳辐射受到削弱。境内地形起伏大,高差悬殊,因此在不同地区、不同海拔、不同坡向所接收到的太阳辐射差异较大热量条件也随之产生差异。
文山州大部分地区冬无严寒,夏无酷暑。干凉和雨热同季,年温差小,日温差大,大陆度不到40%,海洋性气候比较明显,春温高于秋温,无霜期长,霜雪少。年平均气温12.0~23.1℃,≥10℃积温4500~7500℃,初终间日数193~332天。最冷月(1月)平均温度6.5~13.5℃,最热月(7月)平均温度17.0~28.5℃。全年多为偏东南风。低海拔地区炎热,高海拔地区凉爽。由于海拔高低悬殊,故有“山高一丈,大不一样”和“十里不同天”的立体气候特征。
