Air-sea interactions control the exchange of mass, momentum and heat between the atmosphere and the ocean. Substantially, they significantly affect the development of atmospheric and oceanic systems from submesoscale to global scales. Oceanic extremes, i.e., cyclones, storms, freak waves, polar lows, storm surge, etc., pose a significant hazard to offshore activities and coastal society. Air-sea interaction processes are complex and play a central role in the development of those oceanic extremes. Improved understanding of the air-sea interaction processes and describing them in weather models and Earth System Models can improve their prediction and mitigate the potential damages. The energy distribution affected by air-sea interactions can change the large scale circulation and alter the climatology of the oceanic extremes. Despite an overall improvement in the understanding of air-sea interactions, there are still many knowledge gaps, particularly under extreme conditions.

The U.S. Navy's requirement for a computer prediction system for marine fog and stratus dates back to the 1970s when meteorological models were being introduced to the fleet. The Naval Research Laboratory's Coupled Ocean/ Atmosphere Mesoscale Prediction System (COAMPS) is a leap forward in the Navy's numerical modeling ability but it still does not show great skill in fog forecasting. COAMPS has been 'tuned', or adjusted for certain constants and parameterizations, so that it has the minimum error for the maximum area. This tuning is a common practice for all numerical models. The objective of this thesis is to determine if changes can be made to the existing COAMPS code based on reasonable physical experiments for a specific location to help solve the numerical fog forecasting problem. The effectiveness of these experiments was first measured by comparing a modeled cloud edge to satellite imagery of Monterey, California taken during a week in August 2000 under a variety of foggy conditions. Comparisons were also made with observations taken from an aircraft, land stations and a vertical profiler. The experiments, specifically those regarding changes to the autoconversion and turbulent kinetic energy schemes, showed that while a perfect solution has not been found, it is possible to modify the model physics codes and optimize its performance in a specific region.

Marine fog forecasts during the summer period in the North Pacific are not made presently with any acceptable degree of accuracy. Objective fog development models exist and are used with some success for localized coastal regions of the western U.S.; scarcity of accurate data has hindered creation of a reliable open-ocean model. The Eulerian single-station approach, utilizing a segment of the complete accurate data of Ocean Weather Station Papa (50N, 145W) is applied in this study to an objective marine fog forecasting model. The time-series study of significant atmospheric variables at OWS Papa, when coupled with a chronological synoptic overview, delineates accurately fog/no fog sequences in the summer months of 1973 and 1977. Actual observed fog situations are evaluated by the general model and presented in relation to open-ocean fog indices, NOAA 5 satellite coverage and synoptic history. The open-ocean forecast model is tested on an independent data set for the month of July 1975 at OWS Papa, with favorable results. The research delineates four required indices that must all be positive to forecast fog. These indices, when plotted daily in the region of OWS Papa allow a single station to predict, with some confidence out to twenty-four hours, the occurrence of advection fog. (Author).

A major concern to the National Weather Service marine operations is the problem of forecasting advection fogs at sea. Currently fog forecasts are issued using statistical methods only over the open ocean domain but no such system is available for coastal and offshore areas. We propose to use a partially diagnostic model, designed specifically for this problem, which relies on output fields from the global operational Medium Range Forecast (MRF) model. The boundary and initial conditions of moisture and temperature, as well as the MRF's horizontal wind predictions are interpolated to the fog model grid over an arbitrarily selected coastal and offshore ocean region. The moisture fields are used to prescribe a droplet size distribution and compute liquid water content, neither of which is accounted for in the global model. Fog development is governed by the droplet size distribution and advection and exchange of heat and moisture. A simple parameterization is used to describe the coefficients of evaporation and sensible heat exchange at the surface. Depletion of the fog is based on droplet fallout of the three categories of assumed droplet size. Comparison of three months of model results over the Atlantic seaboard with ship data show realistic forecasts of fogbound areas. The MRF initial conditions are used to update the fog model boundaries, thus supplying "perfect forecasts" for the fog model boundary conditions. Liquid water droplet concentrations are used to infer the relative intensity of fog and compare well with visibility reports from ship locations. It should be noted, however, that the verification of fog at sea is hampered by the limited amount of routinely available ship observations. The model also successfully predicted situations in which no fog was present when similarly verified with ship data. These results show that diagnostic models can be developed for specific regional applications based on numerical weather forecasts made with large scale global models.
