# COAMPS-TC Deterministic, Ensemble, and Nowcast Model Support

## Team Members

### **Naval Research Laboratory (NRL)**

- Jim Doyle
- Hao Jin
- Jon Moskaitis

## Team Objectives

Run COAMPS-TC (Coupled Ocean Atmosphere Model Prediction System-Tropical Cyclone) and the 11-member ensemble at high horizontal resolution (4 km) in real time during the 2022-2024 Atlantic and East Pacific hurricane seasons.

Produce approximately 3 hindcasts per year, with accurate tropical cyclone track, size and intensity, over the course of 3 years (for 9 total) for retrospective analysis given highly accurate atmospheric reforecasts and reanalyses.

Facilitate ingestion and analysis of the COAMPS-TC fields in real time for utilization by other teams.

#### Variables produced will include:

- 10-m Winds
- Surface Relative Humidity
- Surface Pressure
- Surface Wind Stresses
- 2-m Air Temperature
- Long Wave and Short Wave Radiation at the Surface
- Surface Latent and Sensible Heat Fluxes
- Surface Net Radiation
- Hourly Precipitation

The 2022 Atlantic Hurricane season is just around the corner, officially beginning on June 1. New for this season, NRL-Monterey will provide deterministic COAMPS-TC® (Coupled Ocean Atmosphere Mesoscale Prediction System – Tropical Cyclone) forecast fields in real-time to NOPP Hurricane Coastal Impacts project partners, for the purpose of forcing surge/inundation/wave model forecasts for landfalling Atlantic tropical cyclones (TCs).
