The seasonal mean tidal height field reference to static mean sea level is calculated, and from which, the mean seasonal circulation obtained based upon geostrophic equations. 根据潮汐模型计算了各季节平均海面距平并进而计算了平均季节环流,初步分析了海面高变化和季节环流的特征。

This value was intended to represent the mean atmospheric pressure at mean sea level at the latitude of Paris, France. 此值代表法国巴黎所在的纬度上平均海拔高度的平均大气压力。
IS the parenthetical figure following DH, DA or MDA which, when added to the touchdown zone, runway end, or threshold elevation, will give the DH, DA or MDA in feet above mean sea level. 决断高度或最低下降高度后括号中的数值。它与接地区、跑道顶端、或跑道头标高相加后即是决断高度(DA,DH)或最低下降高度(MDA)高于平均海平面(MSL)英尺数。
Mass balance of Antarctic ice sheet and mean sea level are the factors in global change study. 南极冰盖的物质平衡和海平面变化是全球变化研究的一个重要内容。
