similar trajectories for varying heights and constant 2) starting level above ground
Posted: August 26th, 2016, 3:29 am
I am using Unified Model output (converted to GRIB2 format) to simulate trajectories.
I could able to successfully convert grib2 file to ARL format using “api2arl” utility. I checked the file and messages after running the hysplit but could not find any error.
I am facing following issues:
1) The trajectory plot shows similar trajectories for different heights.
2) starting level above ground of all trajectories is no varying i.e. constant
Kindly help me to sort these issues. I have attached the message and chkfile and trajplot.ps file for reference.
The control file details are as follows:
16 08 23 18

18.90 72.80 100
18.90 72.80 500
18.90 72.80 1500
18.90 72.80 3500

I tried to change the model name to "ecmwf" (as you see in attached files) but this also resulted in same plots (as attached).
