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).

You can download MeteoInfo 1.3.4 to do this job (http://www.meteothinker.com/news/meteoinfo_1.3.4.html)

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...

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...

I forgot to add attribute to precipitation variable in above script. See revised one: #-------------------------------------------------------- # Author: Yaqiang Wang # Date: 2016-5-6 # Purpose: Convert ARL data to netCDF data # Note: Sample #---------------------------------------------------------...

Please look at below sample script: #-------------------------------------------------------- # Author: Yaqiang Wang # Date: 2016-5-6 # Purpose: Convert ARL data to netCDF data # Note: Sample #----------------------------------------------------------- infn = 'D:/Temp/arl/gdas1.jul09.w5' #Input ARL ...

MeteoInfo/MeteoInfoLab can read ARL data format and there is a sample script for getting meteorological data along trajectory (http://www.meteothinker.com/examples/meteoinfolab/trajectory/traj_meteo_data.html). Using MeteoInfoLab you can also do model verification by specific script. Also it's possi...

You need loading the meteorological data at end of Aug. for backtrajectory calculation starting from the first few days of Sep.

TrajStat document was added online: http://www.meteothinker.com/docs/trajstat/index.html

TSV figure has been added in clustering function of TrajStat Java plugin from 1.4.3 version. So you can get a specified cluster number with the TSV figure using neweast MeteoInfo Java and TrajStat plugin version.
