关于空气质量来源和HYSPLIT人口
显示其他沿Traj变量
我知道如何访问/修改SETUP文件。我怎样才能使HYSPLIT将潜热/显热通量变量显示为沿轨迹变量？这些变量已经在我正在使用的NARR ARL文件中（LHTF，SHTF）。
On the other hand, you could also use the GUI under Meteorology/Display Data/Text Profile to look at the value of the fluxes at fixed latitude and longitudes.
沿轨迹降雨率
For precip, at hours 00, 06, 12, and 18z, the GDAS has the 6-four forecast from the previous cycle.
At hours 03, 09, 15, and 21z, the GDAS has the 3-hour forecast from the current cycle.
如何沿着hysplit轨迹输出涡度。
您可以先计算涡度（http://www.meteothink.org/examples/me ... hdivg.html），然后沿轨迹提取涡度数据（http://www.meteothinker.com/examples/me。 .. _data.html）

METEOINFO
Get meteorological data along trajectory
. After all the changes have been made to the setup menu, press the Save button whichcopies all the information to a special file called default_traj and then closes the menu. Nowthe model simulation can be started from the Trajectory / Run model menu tab. This buttoncauses two actions. First, the trajectory setup information is copied from default_traj to a filecalled CONTROL, which is the input name required by the HYSPLIT trajectory model executable (hyts_std.exe). Second, the GUI then launches the model.
