wrf.g_slp.get_slp()

Bắt đầu với wrf/g_slp.py và lần theo lệnh gọi của nó vào util.py, đặc biệt là extract_vars và _extract_var, nơi traceback cho thấy dữ liệu netCDF được đọc. So sánh các lần tái hiện với timeidx=0 và wrf.ALL_TIMES, đồng thời kiểm tra thao tác truy cập biến bị đình trệ. Được xem là hoàn tất khi get_slp có thể xử lý tất cả các chỉ mục thời gian mà không gặp tình trạng chậm kéo dài như đã báo cáo.

For some reason with this wrf.g_slp.get_slp is having problems reading in the data for all timeidx's. The top one for 1 time index takes 00:00:01 seconds to run. For any of my other variables (T,Td,WS,WDIR, U10, V10, RH) it takes about 5-10 seconds to get the variable for all times. I stopped the code after it seemed to be slowing my computer and was taking more than 10 minutes (on that one command).

I am wondering if there is something wrong in the wrf-python code for this function. I cannot find many other people using this specific function.

ncfile = Dataset(listing[0])
where listing[0] is the wrfout_d03 file.

WORKS
wrf.g_slp.get_slp(ncfile,timeidx=0,method='cat',squeeze=True,cache=None,meta=False,_key=None,units='Pa')

DOES NOT WORK
wrf.g_slp.get_slp(ncfile,timeidx=wrf.ALL_TIMES,method='cat',squeeze=True,cache=None,meta=False,_key=None,units='Pa')
