upper-air wind
解釋
高空風-
In this paper, features of decadal variability and the possible mechanism of sea - air system in the pacific are investigated by using upper - ocean temperature, heat storage and wind stress data, the main results are as follows : the most pronounce decadal sign exists at about 160 meter in depth in the western pacific. there are significant decadal abrupt changes in temperature from surface to deep in the subsurface at about 1980. with different depth in the subsurface, there exist 4 types of abrupt change modes, their generation is closely related to the decadal sign which originates from the east of north pacific and propagates along the south - west subduct ion route
研究表明，太平洋次表層海溫最強的年代際信號在熱帶西太平洋約160m深處，此信號在1980年前後從上至下，先後經歷了一次顯著的年代際突變過程，而且隨深度的不同存在著四種不同的空間突變模態，這四種模態的形成與北太平洋海溫異常的西南潛沉路徑有著密切的聯系。 -
Upper - air vector mean wind
高空平均矢量風 -
The results show that the weather process occurs because of typhoon trough with cold air, deep upper trough ; the southeast low - jet by typhoon transported large water vapour and great energy of instability to heavy rainfaill area ; cold air, lower convergence and upper divergence by deep upper trough lead to development of the east - ocean low pressure and occurd strong wind
分析結果表明：這次天氣過程是由臺風倒槽和冷空氣及深厚的高空槽共同作用引起的；臺風環流引起的東南低空急流為暴雨區輸送了大量的水汽和不穩定能量；冷空氣的侵入加上深厚的高空槽引起的低空輻合、中高層輻散，促使了東海低壓的劇烈發展，產生了猛烈的大風。 -
In transforming stage the intruding of cold air intensifies convergence in lower level, which makes for kinetic energy generation and favors to cyclone maintaining. in reintensifying stage the effect of upper jet increases kinetic energy generation by divergent wind in lower level, which causes baroclinic developing in cyclone
在變性階段，由於冷空氣的侵入使低層的動能製造增加，對臺風的維持起了主要的作用在重新加強階段，高空急流的影響使低層散度風的動能製造明顯增加，使氣旋斜壓不穩定發展。 -
Measurement of upper air winds - wind profiler in chinese only
高空風向和風速的探測-氣流剖析儀 -
Apart from the original set of surface charts on temperatures, wind direction and wind speed, mean sea level pressure and weather conditions, the contents of the new computer upper - air forecast charts include spatial distributions of key weather elements at four different layers within the troposphere, as well as an explanatory note to facilitate understanding and application by the general public
內容方面，除原有的地面溫度、地面風向及風速、平均海平面氣壓及天氣情況外，新增的電腦預測圖提供在大氣對流層內四個不同高度的層面的主要氣象資訊，以及一些相關的解釋，方便市民理解及使用。 -
Four upper air measurements of wind, pressure, temperature and humidity are carried out daily at 0200h, 0800h, 1400h and 2000h local time
天文臺每日定時在香港時間2時、 8時、 14時及20時作四次高空探測，量度高空風向、風速、氣壓、氣溫及濕度。
