这些预测

• The information is generated by the observatory s high - speed computer using physical models and mathematical equations to simulate the evolution of weather systems . the computer simulations are presented as maps showing the surface temperature , surface wind speed and wind direction , mean sea level pressure and the state of the sky at various locations
  这些预测资料是利用天文台高速电脑根据物理定律及数学方法计算出来的，以天气图显示，内容包括地面温度、地面风向及风速、平均海平面气压及天气的大致情况。
