| Use Canuto/Kitamura mod (remove Ric and negative TKE) (1:yes, 0:no) For more info, see Canuto et al. (2008 JAS) and Kitamura (Journal of the Meteorological Society of Japan, Vol. 88, No. 5, pp. 857-864, 2010). Note that this change required further modification of other parameters above (c2, c3). If you want to remove this option, set c2 and c3 constants (above) back to NN2009 values (see commented out lines next to the parameters above). This only removes the negative TKE problem but does not necessarily improve performance - neutral impact. More... | |
