Re: met text to ARL format
It's possible to do it with a MeteoInfoLab script. Please find online example on it (http://www.meteothinker.com/examples/me ... b2arl.html).

Re: Clustering with Different Start Heights
Hello.. i am doing cluster analysis in hysplit but now i want to try it in trajstat. After drawing all trajectories in trajstat i convert them in line data file (lcd) but when i tried to do cluster analysis it is showing an error " Each trajectory line should has same end points". I am not able to ...

Re: how to output vorticity along the hysplit trajectory.
You may calculate vorticity firstly (http://www.meteothinker.com/examples/me ... hdivg.html) and then extract the vorticity data along the trajectory (http://www.meteothinker.com/examples/me ... _data.html).

Re: Error in vertical velocity and meteorological variables along the trajectory
In this case vertical levels are in normal order, so you don't need to reverse them. Revised script: #---- Set data folder datadir = 'E:/Temp' #---- Set output data file outfn = os.path.join(datadir, 'test_grib.arl') #if os.path.exists(outfn): # os.remove(outfn) #---- Read a GRIB data file infn = os...

Multi-color trajectory plot
Only one color can be assigned to a line in MeteoInfo, so we have to create multi-line pieces to fullfill multi-color trajectory plot function. Below is an example to plot a multi-color trajectory according to it’s height. Read the endpoints from the HYSPLIT output trajectory file, and create a laye...
