| Dear all, I am running RegCM3 for year 2000, everything was working fine initially until I got to April and it started displaying the following. I used prescribed dt =3*dx , my dx=25km and my dt =75. Can anyone tell me what went work. *** solar declination angle = 22.67 degrees. dectim = 894240.000000000 OUT-history written date = 2000060500.00000 BATS variables written at 2000060500 0.000000000000000E+000 Writing rad fields at ktau = 178560 2000060500 BCs are ready from 2000060500 to 2000060506 at day = 155.0339, ktau = 178600 : 1st, 2nd time deriv of ps = NaN NaN , no. of points w/convection = 0 regcm.in $restartparam ifrest = .false., idate0 = 2000010200, idate1 = 2000010200, idate2 = 2000123100, nslice = 120, $ $timeparam radfrq = 30., abemh = 20., abatm = 600., dt = 75., ibdyfrq = 6, $ $outparam ifsave = .true. , savfrq = 48., iftape = .true. , tapfrq = 1., ifrad = .true. , radisp = 1., ifbat = .true. , ifsub = .true. , batfrq = 1., ifprt = .false., prtfrq = 12., kxout = 6, jxsex = 40, iotyp = 1, ibintyp = 1, ifchem = .true. , chemfrq = 6., $ $physicsparam iboudy = 5, ibltyp = 1, icup = 2, igcc = 2, ipptls = 1, iocnflx = 2, ipgf = 0, lakemod = 0, ichem = 0, $ $subexparam ncld = 3, qck1land = 0.00025, qck1oce = 0.00025, cevap = 1.0e-3, caccr = 3.0, $ $grellparam $ $emanparam $ $chemparam idirect = 2, chtrname = 'SO2', chtrsol = 0.20, chtrdpv = 0.00300,0.00800, dustbsiz = 0.01, 1.00, $ Present address Vincent Lanre Ajayi START-ACCFP fellow Climate Systems Analysis Group Dept of Environmental & Geographical Science University of Cape Town Private Bag X3 Rodebosch 7701 Cape Town, South Africa office:+27216505774 Mobile: +27834262253 Permanent Affiliation Department of Meteorology School Earth and Mineral Sciences, Federal University of Technology, PMB 704 Akure 340001,Nigeria, voajayi@futa.edu.ng skype:vincentajayi1 |
