Forecasting Sea Fog


Forecasting sea fog events are becoming more effective in the modern world. The efficiency of sea fog forecasts are due to more detailed analyses of turbulent and moisture transportation within the marine boundary layer.

Previous knowledge of the initial temperature and moisture components of the boundary layer is helpful for providing a potentially accurate sea fog forecast. These components are used in models to produce fairly accurate humidity level forecasts, thus providing information on a potential sea fog event. Besides moisture and temperature, advected sea fog model predictions depend also on the hydric state of the soil of the land surface. Steam sea fogs are rarely forecasted because of their relatively low occurrences and generally low inability to affect traffic systems or humans in some particular occasion.


The most important objection for future forecasting of sea fog events will be earliest warnings of potentially hazardous dense sea fog. This early warning will aid traffic systems in providing detailed information to personal, so they can pass crucial information along to their users. The more detailed information the public system receives from early-warning forecasts may result in a decrease in hazardous occurrences from such sea fog events.

The observation and model used to forecast a sea fog event. The model used wind speed, humidity, air temperature, and sea surface temperature to forecast sea fog formation in the morning hours of a stable atmosphere. The model exaggerates the amount of sea fog production that occurred. The main contributor to this exaggeration is the wind speed estimation over the sea surface in the middle of the night (near midnight local time). This increased the sea fog production earlier in the morning hours within the model, but the observation shows the sea fog event occurred just before sunrise.
