摘要 本文试图估计冬季安大略湖上方约 1 至 15 m 的水面空气温度和露点温度。多元统计技术用于制定回归模型，其中包含容易确定的变量，例如陆地温度、地表水温、风速和水上取水。 71% 到 92% 的方差可以由所得模型解释，空气温度的平均标准误差为 1.1°C，露点温度的平均标准误差为 1.4°C。研究发现，低层大气中超过一半的变化发生在开放水域的前 10 分钟或前 1-2 英里内。通常，从陆地到湖泊的气温变化很少超过潜在温度的 60%，因为它受到地表水温的限制，并且在非常冷的空气中几乎不会达到 40%。对于选定的冬季天气情况，检查温度、湿度以及感热通量和蒸发通量的空间变化......
Abstract This paper attempts to estimate over-water air temperatures and dew-point temperatures between about 1 and 15 m above Lake Ontario in winter. Multivariate statistical techniques are used to formulate regression models incorporating readily determined variables such as over-land temperatures, surface water temperatures, wind speed, and over-water fetch. Seventy-one to 92 percent of the variance can be accounted for by the resultant models with average standard errors of 1.1°C for air temperature and 1.4°C for dew-point temperature. More than half of the modification in the lower atmosphere was found to occur in the first 10 min or over the first 1–2 mi of open water. Usually the change in air temperature from land to lake seldom exceeds 60 percent of the potential because it is limited by surface water temperature and barely reaches 40 percent with very cold air. For selected winter weather situations, the spatial variations of temperature, humidity, and sensible and evaporative fluxes are examine...
