【温带气旋过境】 0. 前几天看wind aloft发现周日1500ft层面风有居然都有60节(数据来自GFS的数值),就知道事情会很有趣。看了prog chart,果然是温带气旋。今天下午1点左右,地面中心最低气压到了985hPa。旧金...

Air in contact with the ground becomes cold while the temperature a few hundred feet above changes very little. Thus, temperature increases with height. Inversions may also occur at any altitude when conditions are favorable. For example, a current of warm air aloft overrunning cold air near ...
Troposphere - the bottom few miles of the air's depth. Temperature decrease with height at an average rate of almost 6°C per km. Tropopause - the division between the troposphere and stratosphere temperature suddenly stops decreasing with height at this level. Stratosphere - a stable layer imm...

Using high-flying wind turbines on ships could contribute alot of useful meteorological knowledge. Just think of all the temperature, humidity, and wind velocity data a ship could collect if it had sensors regularly spaced along the tether to its wind turbine.Alternative...

where g is the gravitational acceleration (9.81 m/s2), θv is the virtual potential temperature, Δθv,Δθz,Δu, and Δv are the difference in virtual potential temperature, height, the u component of wind, and the v component of wind and between a certain height and surface. (2) ...
The AWOS, manufactured by Vaisala, Finland, is installed at three locations: the southern end, the midpoint, and the eastern side of the northern end of the runway, 300 m from each end. The observed data comprise temperature, humidity, atmospheric pressure, wind direction, and wind speed, ...
