Creates and draws a vector plot over a polar stereographic map projection, and uses a scalar field to draw a separate contour plot or color the vectors. D Candidate, Department of Civil and Environmental Engineering, The University of Western Ontario, London,. I wish NCL didn’t do this, because each figure needs to be “re-tuned” to make sure there’s no overlap. The precipitation data set used by NARR comes from different sources, including the CPC Merged Analysis of Precipitation (CMAP), a merged combination of satellite and gauge precipitation. There are also some programs such as NSHARP and BUFKIT that are more full featured. load "WRFOptions. 0015), despite 6e gradient has reversed ahead of precipitation for 4-5 years.
