中文摘要:
      天气数值预报研究中对预报问题的提法与日常天气预报工作中由天气历史演变来作预报的那种提法是很不相同的.本文对大尺度运动讨论了这两种提法在一定的简单附加条件下是等值的.由此也说明地面温压场的演变反映了也蕴含了斜压大气三维温压场的构造,并且决定了斜压大气三维温压场的发展.
英文摘要:
      Weather forecasting is formulated as an initial value problem in the work of numerical forecasting, while in the routine forecasting in the conventional way it is formulated as, an 0evolution' problem of weather process, especially that on certain specific level. It is shown in this paper that for large-scale motion these two different formulations are in fact equivalent under certain trivial conditions. It is also pointed out that for large-scale motion the three-dimensional structure of the baroclinic atmosphere at certain moment is reflected in and could be reconstructed from the evolution of the contour and temperature fields at certain level before and after that moment.
