Note: general variable declaration grammar is: Var n1 n2 Xa a1 a2 ... Pb b1 b2 .... op Tc c1 c2 c3 c4 .... where Var-name of variable n1-KPDS(5) n2-KPDS(6) X is M|H|D M-symbol for mean/spread H-symbol for accumulated mean/spread symbol D-symbol just for other derived variables a-number of levels at which mean/spread will be calculated (maximum = 40, if larger than 40, modify maxmlvl in parm.inc file) a1, a2, ..ai, list of levels defined by KPDS(7), i=a P-symbol for probability b-number of levels at which probability will be calculated (maximum = 40, if larger than 40, modify maxplvl in parm.inc file) b1, b2, ..bj, list of levels defined by KPDS(7), j=b op-one of three threshold comparison opertors: >|<|= T-sybol for threshold in probability computation c-number of thresholds (maximum = 25, if larger than 25, modify maxtlvl in parm.inc file) c1, c2, ..ck, list of thresholds, k=c Derived variables: current only following Derived variables can be specified (1) Thickness -> height must be declared (2) Accumulated precipitation -> precipitation must be declared (3) Accumulated snow -> precipitation and rain,freez rain, ice must be declared (4) Precipitation type -> rain,freez rain, ice must be declared (5) Dominant precipitation -> rain,freez rain, ice must be declared (6) Wind speed -> U and V component must be declared if a variable already is declared for mean/spread, this variable needs no declare again If want to get products other than these 6 variable, please contact Binbin Zhou to add it into the program examples: (1) T2m 11 105 M1 2 P1 2 < T1 273.0 This declaration is: compute 2m mean and spread of temperature at 2m and its probability of < 273K Note, this declaration can be splitted into two declarations: T2m 11 105 M1 2 T2m 11 105 M0 P1 2 < T1 273.0 (2) PWTR 54 200 M1 0 This declaration is: compute mean and spread of potential water, no probability computation (3) POP 193 1 M0 P1 0 = T1 1.0 This declaration is: compute probability of rain, no mean/spread is required to compute (4) T 11 100 M4 850 700 500 300 P4 850 700 500 300 < T1 273 This declaration is: compute mean and spread of temperature at 850 700 500 300mb respectively, and compute probability of temperature < 373K at 850 700 500 300mb respectively (5) APAC 61 1 H4 3 6 12 24 P4 3 6 12 24 > T8 0.25 1.27 2.54 6.35 12.7 25.4 38.1 50.8 This declaration is: compute 3,6,12,24hr accumulated precip and their probability > 0.25 1.27 2.54 6.35 12.7 25.4 38.1 50.8 This this declaration can be splitted into: APAC 61 1 H1 3 P1 3 > T8 0.25 1.27 2.54 6.35 12.7 25.4 38.1 50.8 APAC 61 1 H1 6 P1 6 > T8 0.25 1.27 2.54 6.35 12.7 25.4 38.1 50.8 APAC 61 1 H1 12 P1 12 > T8 0.25 1.27 2.54 6.35 12.7 25.4 38.1 50.8 APAC 61 1 H1 24 P1 24 > T8 0.25 1.27 2.54 6.35 12.7 25.4 38.1 50.8 (6) THKN 7 101 M1 21860 1000 850 This declaration is: compute 1000-850 layer thickness mean adn spread (7) PRCP 61 1 D1 0 This declaration is: just declare it for accumulated precip computation
