热平衡显示相同的温度……海风活跃季节在我们在佛罗里达(6月初- 9月下旬),这意味着温度一般在80年代低°F(上20°C)……这将是最常见的日落之后\上午。洋流可能意味着一些地区有很多冷却器(甚至温暖)水比陆地气团在很长一段时间。所以有很多地方很长一段的海风时倾向于保持相当强劲(例如,加州太平洋沿岸的春季和夏季)(可能是显而易见的,人们在大多数地区,但我提醒自己,海风并不等同于雷暴在大多数地区大部分的时间!)你会希望在这样一个时间条件反映当时的天气条件下(通常的相互作用引起的大规模区域条件瞬态高、低压力,气团运动,垂直不稳定和混合)。注意:这并不意味着风肯定会平静的大海和陆地在相同温度下……通常有一些区域压力梯度(最小梯度往往局限于广泛的高压区域和关口附近)……和其他因素;为我佛罗里达的情况,上午的时候风经常开始增加,因为加热引起的垂直混合带来更强的风速度从高空向水面。 All that, plus the reduced friction over water, mean seashores\large lakeshores tend to be some of the rarer land locations to see calm winds, as [this hourly August wind climatology of a coastal Florida site shows][1] (they only see calm winds [4.5% of the time][2]) - Likewise the wind can go calm at the seashore at times even when a large thermal imbalance exists... if the synoptic conditions oppose the local thermally-induced sea-land pressure gradient. A rough idea of the conditions that do this would be: In the Northern Hemisphere, the synoptic winds should oppose the seabreeze if synoptic low pressure is off to the left \ synoptic high pressure is off to the right when looking at the ocean along a regionally representative shoreline during the daytime... And the synoptic winds will oppose the landbreeze if synoptic low pressure is off to the right \ synoptic high pressure is off to the left when looking at the ocean along a representative shoreline during the night\early morning. (Flip directions for SH) Also it's worth noting that seabreeze boundary "fronts" can penetrate quite far inland and take time to fade away... even after temperatures have equalized at the shoreline or the landbreeze has started to develop near the coast... and if there are thunderstorms along the seabreeze boundaries, the [cool air released by the rainfall][4] often further reinforces the thermal gradient... I've certainly seen seabreeze boundaries persist deep into the night hundreds of miles from the coast.
