Joe Cione and Erica Rule represented AOML at the Marlins Park for WFOR CBS Miami’s Weather Day. Over 10,000 school children came to the event before the 12:40 game between the Miami Marlins and the New York Mets.
The Miami-South Florida Weather Forecast Office also participated, showcasing a weather balloon and the tornado simulator. Joe and Erica showed a dropwindsonde like those released from Hurricane Hunter aircraft to measure wind, temperature, and humidity in the hurricane, and the Coyote Unmanned Aircraft System that AOML hopes to test this year during a hurricane flight to obtain observations near the ocean surface.

NOAA-42 is scheduled for a test flight tomorrow (8/14) with a take off time of 10AM. This flight is to test the unmanned aerial system called Gale. The Gale will be launched from the P-3. If the flight is successful, we might use the Gale in the future to sample tropical cyclones. We have an experiment in our field program plan that describes how we would use the Gale.

NOAA42 is scheduled for an Ocean Heat Content flight this Thursday (8/16). The primary goal of this flight is to sample the eastern Gulf of Mexico. There is an ocean eddy and a cold region just northeast of the Yucatan Peninsula that is of research interest. The plan is to drop ocean measuring expendable instruments such as (AXCPS, AXBTs and AXCTDs) to sample the ocean. To learn more on past experiments on ocean sampling click here.
Dr. Joe Cione gave a seminar entitled “HWRF Evaluation: Phase I- Hurricane Air-Sea Interaction” at ESRL Physical Science Division on 26 July.
The proposed hurricane model evaluation and improvement effort is envisioned as a multi-stage project that includes several iterative phases. The initial stage begins with an in-depth inter-comparison of model and observational hurricane air-sea fields. This particular region of the storm will be analyzed first since it is believed that existing air-sea observations can adequately describe the mean and asymmetric state associated with this region of the hurricane (i.e. wave numbers 0/1). As such, properly scaled analyses derived from operational model output should enable a realistic and reasonably accurate assessment of model performance (relative to observations) as it relates to this critically important region of the storm. The specifics associated with “phase I” of this effort will include operational runs from 2011 using HWRF 3.2 output in addition to buoy observations collected at the same time and physical location. Multi-storm, composite air-sea analyses will also be presented comparing HWRF 3.2 fields with observations from the Tropical Cyclone Buoy Database (Cione et al. 2000, Cione and Uhlhorn 2003). In addition to analyses evaluating current model air-sea performance, a more general discussion of the goals, methodology and possible next steps forward associated with the proposed model evaluation and improvement effort will also be presented.

HRD held a two-day off-site science retreat at the Miami Beach Coast Guard Base. With assistance from the Federal Mediation & Conciliation Service (Ines DelGado, Commissioner, facilitated the retreat), HRDers discussed ways to strengthen their scientific visibility, work environment cohesiveness, and future science directions. The retreat provided an open forum for the group to explore these topics.
