c !IROUTINE: capecalc3d -- Calculate CAPE and CIN
c
c !DESCRIPTION:
c
c If i3dflag=1, this routine calculates CAPE and CIN (in m**2/s**2,
c or J/kg) for every grid point in the entire 3D domain (treating
c each grid point as a parcel). If i3dflag=0, then it
c calculates CAPE and CIN only for the parcel with max theta-e in
c the column, (i.e. something akin to Colman's MCAPE). By "parcel",
c we mean a 500-m deep parcel, with actual temperature and moisture
c averaged over that depth.
c
c In the case of i3dflag=0,
c CAPE and CIN are 2D fields that are placed in the k=mkzh slabs of
c the cape and cin arrays. Also, if i3dflag=0, LCL and LFC heights
c are put in the k=mkzh-1 and k=mkzh-2 slabs of the cin array.

C The comments were taken from a Mark Stoelinga email, 23 Apr 2007,
C in response to a user getting the "Outside of lookup table bounds"
C error message.
C
C TMKPARI - Initial temperature of parcel, K
C Values of 300 okay. (Not sure how much from this you can stray.)
C
C PRSPARI - Initial pressure of parcel, hPa
C Values of 980 okay. (Not sure how much from this you can stray.)
C
C THTECON1, THTECON2, THTECON3
C These are all constants, the first in K and the other two have
C no units. Values of 3376, 2.54, and 0.81 were stated as being
C okay.
C
C TLCL - The temperature at the parcel's lifted condensation level, K
C should be a reasonable atmospheric temperature around 250-300 K
C (398 is "way too high")
C
C QVPPARI - The initial water vapor mixing ratio of the parcel,
C kg/kg (should range from 0.000 to 0.025)

c Historically, this routine calculated the pressure at full sigma
c levels when RIP was specifically designed for MM4/MM5 output.
c With the new generalized RIP (Feb '02), this routine is still
c intended to calculate a set of pressure levels that bound the
c layers represented by the vertical grid points, although no such
c layer boundaries are assumed to be defined. The routine simply
c uses the midpoint between the pressures of the vertical grid
c points as the bounding levels. The array only contains mkzh
c levels, so the pressure of the top of the uppermost layer is
c actually excluded. The kth value of pf is the lower bounding
c pressure for the layer represented by kth data level. At the
c lower bounding level of the lowest model layer, it uses the
c surface pressure, unless the data set is pressure-level data, in
c which case it assumes the lower bounding pressure level is as far
c below the lowest vertical level as the upper bounding pressure
c level is above.

C ***************************************************************
C * Storm Relative Helicity (SRH) is a measure of the *
C * streamwise vorticity within the inflow environment of a *
C * convective storm. It is calculated by multiplying the *
C * storm-relative inflow velocity vector (Vh-C) by the *
C * streamwise vorticity (Zh) and integrating this quantity *
C * over the inflow depth (lowest 1-3 km layers above ground *
C * level). It describes the extent to which corkscrew-like *
C * motion occurs (similar to the spiraling motion of an *
C * American football). SRH corresponds to the transfer of *
C * vorticity from the environment to an air parcel in *
C * convective motion and is used to predict the potential *
C * for tornadic development (cyclonic updraft rotation) in *
C * right-moving supercells. *
C * *
C * There is no clear threshold value for SRH when forecasting *
C * supercells, since the formation of supercells appears to be *
C * related more strongly to the deeper layer vertical shear. *
C * Larger values of 0-3-km SRH (greater than 250 m**2/s**2) *
C * and 0-1-km SRH (greater than 100 m**2/s**2), suggest an *
C * increased threat of tornadoes with supercells. For SRH, *
C * larger values are generally better, but there are no clear *
C * "boundaries" between non-tornadic and significant tornadic *
C * supercells. *
C * *
C * SRH < 100 (lowest 1 km): cutoff value *
C * SRH = 150-299: supercells possible with weak tornadoes *
C * SRH = 300-499: very favorable to supercell development and *
C * strong tornadoes *
C * SRH > 450 : violent tornadoes *

SUBROUTINE CALCDBZ(DBZ,PRS,TMK,QVP,QRA,QSN,QGR,WEDIM,SNDIM,BTDIM,
+ SN0,IVARINT,ILIQSKIN)
c
c This routine computes equivalent reflectivity factor (in dBZ) at
c each model grid point. In calculating Ze, the RIP algorithm makes
c assumptions consistent with those made in an early version
c (ca. 1996) of the bulk mixed-phase microphysical scheme in the MM5
c model (i.e., the scheme known as "Resiner-2"). For each species:
c
c 1. Particles are assumed to be spheres of constant density. The
c densities of rain drops, snow particles, and graupel particles are
c taken to be rho_r = rho_l = 1000 kg m^-3, rho_s = 100 kg m^-3, and
c rho_g = 400 kg m^-3, respectively. (l refers to the density of
c liquid water.)
c
c 2. The size distribution (in terms of the actual diameter of the
c particles, rather than the melted diameter or the equivalent solid
c ice sphere diameter) is assumed to follow an exponential
c distribution of the form N(D) = N_0 * exp( lambda*D ).
c
c 3. If ivarint=0, the intercept parameters are assumed constant
c (as in early Reisner-2), with values of 8x10^6, 2x10^7,
c and 4x10^6 m^-4, for rain, snow, and graupel, respectively.
c If ivarint=1, variable intercept parameters are used, as
c calculated in Thompson, Rasmussen, and Manning (2004, Monthly
c Weather Review, Vol. 132, No. 2, pp. 519-542.)
c
c 4. If iliqskin=1, frozen particles that are at a temperature above
c freezing are assumed to scatter as a liquid particle.
c
c More information on the derivation of simulated reflectivity in
c RIP can be found in Stoelinga (2005, unpublished write-up).
