The spatial distribution of total water vapor content over the Yamal Peninsula and adjacent territories was analyzed using data of four-year-long measurements from the European Envisat satellite during warm periods of the year (June-August). Special attention was given to water vapor variations at the transition from little to abundant water-bearing areas of the underlying surface. It was found that for the five selected sites located in a dry tundra and in large water bodies the logarithmic rather than Gaussian form of the distribution functions of total water vapor content turned out to be typical according to the number of its measurements. Each function has at least two modes. The parameters of these modes were calculated and presented, and they are necessary for simulation of climatic conditions in the northern territories. Geometric mean values of total water vapor content over the Gulfs of Gydan and Baidaratsk, and especially over the Gulf of Ob, can be by a factor of 1.5 larger than those for the less water-abundant areas of tundra and have clear boundaries coincident with geographical contours of the water bodies. It is most likely that these boundaries exist at insignificant speeds of surface winds, which is indicative of weak turbulent mixing of the lower air layers. This conclusion is confirmed by results from processing published data of ground-based and satellite observations. For the five sites they were used to calculate and construct the wind roses for all five sections in the same time intervals when the satellite measurements of water vapor content were carried out. Wind rose analysis shows that the average velocity of predominantly N and NW winds on all the selected sites at a height of 10 m above the underlying surface are 5–6 m/s with a standard deviation of 1.5 m/s. Additional data are presented on the form of the distribution function of various parameters in other natural environments (water bodies and vegetation) which give support to what has been said above about water vapor.

亚马尔年暖期水汽总含量

使用欧洲环境卫星卫星在一年中温暖时期（6 月至 8 月）的四年测量数据分析了亚马尔半岛和邻近领土上总水汽含量的空间分布。特别注意下垫面含水量从少到多的过渡区的水汽变化。结果发现，对于位于干燥苔原和大型水体中的五个选定地点，总水蒸气含量分布函数的对数形式而不是高斯形式根据其测量次数证明是典型的。每个功能至少有两种模式。这些模式的参数被计算和呈现，它们对于模拟北部地区的气候条件是必要的。吉丹湾和拜达拉茨克湾，尤其是鄂毕湾的总水汽含量的几何平均值，比苔原水分较少的地区大 1.5 倍，并且具有与地理区域一致的清晰边界。水体的轮廓。这些边界很可能以微弱的地表风速存在，这表明较低空气层的湍流混合较弱。这一结论得到了处理已发表的地面和卫星观测数据的结果的证实。对于五个站点，当进行水汽含量的卫星测量时，它们被用来计算和构建所有五个部分在相同时间间隔内的风玫瑰图。风玫瑰图分析表明，在所有选定地点在下垫面上方 10 m 高度处，主要为 N 和 NW 风的平均速度为 5-6 m/s，标准偏差为 1.5 m/s。提供了关于其他自然环境（水体和植被）中各种参数分布函数形式的附加数据，这些数据支持上述有关水蒸气的内容。
