Add Support to Interpolate for Commonly Used Parameters

[xebadir]

Many parameters are calculated by interpolating some parameter against a reference coordinate (T, P, HAGL, H) - need to implement code that could wrap interpolation for:
2-4km AGL Lapse rate. (interpolate temperatures to height AGL level and difference, divide by height difference)
700-500mb LAPSE Rate (interpolate temperatures to pressure level and difference, divide by height difference)
500mb Temperature (in C) (interpolate temperature to pressure level)
0-6km Shear, 0-1km shear (interpolate u, v to height agl, and then take vector difference relative to surface level).

Example Code for the old way:
LAPSE = np.zeros((ny,nx)) T500 = np.zeros((ny,nx)) LAPSE_3km = np.zeros((ny,nx)) LAPSE_24km = np.zeros((ny,nx)) THGZ = np.zeros((ny,nx)) for i in range(0,nx): for j in range(0,ny): if(T[0,j,i]>0.0): if(P[0,j,i]>=700.): T700 = vinterp3d.dinterp3dz(T[:,j,i],P[:,j,i],700.) T500[j,i] = vinterp3d.dinterp3dz(T[:,j,i],P[:,j,i],500.) Z700 = vinterp3d.dinterp3dz(H[:,j,i],P[:,j,i],700.) Z500 = vinterp3d.dinterp3dz(H[:,j,i],P[:,j,i],500.) LAPSE[j,i]=(T700-T500[j,i])/((Z500-Z700)/1000.) T3km = vinterp3d.dinterp3dz(T[:,j,i],AGLH[:,j,i],3000.) HT30 = vinterp3d.dinterp3dz(H[:,j,i],T[:,j,i],-30.) HT10 = vinterp3d.dinterp3dz(H[:,j,i],T[:,j,i],-10.) T4km = vinterp3d.dinterp3dz(T[:,j,i],AGLH[:,j,i],4000.) T2km = vinterp3d.dinterp3dz(T[:,j,i],AGLH[:,j,i],2000.) LAPSE_3km[j,i]=(T[0,j,i]-T3km)/3. LAPSE_24km[j,i]=(T2km-T4km)/2. THGZ[j,i]=HT30-HT10

S06 = np.zeros((ny,nx)) u6km = vinterp3d.dinterp3dz(U[:,:,:],AGLH[:,:,:],6000.) v6km = vinterp3d.dinterp3dz(V[:,:,:],AGLH[:,:,:],6000.) S06[:,:] = np.sqrt((u6km[:,:] - U[1,:,:])**2 + (v6km[:,:] - V[1,:,:])**2)

Cleaning up Feature request above:

• T700, T500 = intepolate T on P
• Z700, Z500 = interpolate AGLH/H on P (since we use the difference in LAPSE, we can use either AGLH or H.
• LAPSE = (T700-T500)(z500-z700)/1000 (in km)
• T2km, T3km, T4km = interpolate T on AGLH
• LAPSE3km = (T3km-Ts)/3
• LAPSE24km = (T4km-T2km)/2
• HTminus30, HTminus10 = interpolate AGLH on T
• THGZ = HTminus30 - HTminus10
• U1km, V1km, U6km, V6km = interpolate U,V on AGLH
• S06km = ( (U6km-Us)**2 + (V6km-Vs)**2 )**0.5
• S01km = ( (U1km-Us)**2 + (V1km-Vs)**2 )**0.5

Note all of the parameters with height references should be AGL interpolated.
