Ongoing analyses will lead to a database of surface flux fields and CBL characteristics that will enable quantitative and rigorous tests of surface-CBL coupling, and provide validation for high resolution numerical simulations with MM5. These databases, which will be made available to the IHOP and broader atmospheric sciences community, will be described.
The cases captured by IHOP observations, as well as preliminary results and hypotheses will be reviewed. Phenomena that are captured include highly heterogeneous land surface forcing at a variety of scales, and varying response by the CBL, wave structures, and detailed characterization of the CBL entrainment zone. At the largest scales, CBL depths and moisture content varied by as much as a factor of two, but in other cases strong potential temperature inversions limited the heterogeneity in CBL depth. Many cases showed evidence of widespread wave structure within and above the CBL. These waves may be a significant source of CBL modulation that is independent of heterogeneous land surface forcing. Cases where surface flux heterogeneity led to favored locations for convective initiation were not immediately apparent, but the pre-conditioning of the CBL was clearly heavily dependent on the surface energy budget.
