Add option for where to place warm bubble and perturbation temperature for idealized supercell case.
Also enhanced control over location and size of perturbation bubble for em_quarter_ss. Includes option to initialize along a line instead of a cellular bubble!
-Superimposed divergence in ideal ICs -Modified the structure of the initialization W field for ideal -Modified checks in diagnostics code to allow history_interval = 0 to be set with history_interval_[dhms] /= 0 for greater control over output interval
…esetting max precip rates.

@Jeff-Duda Can you rebase your change to the latest WRF release code v4.8.0 and target to develop branch? The regression tests are not able to point to earlier releases of MMM-physics code. Thanks. |

@weiwangncar I think I can handle that. The work is not a priority at the moment, so this PR will probably hang for awhile until I can free up some time to get to the work. If that is too long, then let me know and I can either push this up in my priority list or we can delete the PR and I can re-institute it at a later time. |

@Jeff-Duda Thanks for your reply. We still have time for 4.8.1 release. I will let you know when we get close. |

Purpose: to add arrays to WRF microphysics to calculate maximum precipitation rate over fixed (sub-hourly) periods
TYPE: enhancement
KEYWORDS: precipitation, microphysics, maximum, rate, diagnostics
SOURCE: Jeff Duda, CU/CIRES and NOAA/GSL
DESCRIPTION OF CHANGES:
Problem:
(1) Current code does not include maximum precipitation rates, especially over sub-hourly intervals. Time-maximum composite reflectivity is also absent.
(2) This particular code change also includes modifications to the methods of initializing convection in the idealized supercell test case
Solution:
Modified the microphysics_driver and diagnostics code to include these arrays.
ISSUE: None
LIST OF MODIFIED FILES:
M Registry/Registry.EM_COMMON
M dyn_em/module_initialize_ideal.F
M dyn_em/module_stoch.F
M dyn_em/solve_em.F
M phys/module_diag_misc.F
M phys/module_diag_nwp.F
M phys/module_diagnostics_driver.F
M phys/module_microphysics_driver.F
M share/module_check_a_mundo.F
TESTS CONDUCTED:
RELEASE NOTE: Added 1-, 5-, 10-minute maximum precipitation rate and history-interval-maximum composite reflectivity to available outputs. Also enhanced convection initiation mechanism in idealized supercell case by offering additional user controls.
