A climatology of the Cape Canaveral, Florida sea breeze has been established using data from the warm seasons of 1995 and 1996. Data from the Cape Canaveral mesoscale tower network were used to locate the sea breeze, determine its inland penetration, and assess its time of passage. Visible satellite imagery centered over Melbourne, Florida also were used for this purpose. Radiosonde data were used to determine the large-scale flow over the region. A total of 357 days was analyzed. These days...

Numerical models for nearshore circulation patterns in the surf zone were developed and applied to an observed condition subjected to a sea breeze environment. Bottom topography and input waves were derived from observed data to predict surf zone circulation as a function of time of day. It was found that many features observed in the surf zone were modeled but wave-current interactions are known to be important. Wave-current interactions were modeled for shallow water assuming a...

Real data tests of a single-Doppler radar data assimilation and forecast system have been conducted for a Florida sea breeze case. The system consists of a hydrostatic mesoscale model used for prediction of the preconvective boundary layer, an objective analysis that combines model first guess fields with radar derived horizontal winds, a thermodynamic retrieval scheme that obtains temperature information from the three-dimensional wind field and its temporal evolution, and a Newtonian nudging...

Information on the structure of the sea breeze obtained by previous observational and theoretical studies has been employed to formulate a kinematic model of the wind field associated with the sea breeze. Existing information on the structure of the stabilized fallout cloud has been compiled for use in the numerical computation of the deposition of the cloud particles through specified local wind fields. A program was constructed for the numerical computation of fallout transport through an...

Model local circulations are discussed with regard to their influence on the disposition of airborne particles in a non-precipitating, nondiffusive atmosphere. Two-dimensional vertical circulations like the sea breeze along a straight coast, or like the circulations near mountain ranges, when steady- state, principally affect the time of establishment of a pattern and not its shape or the ultimate patterns of the total accumulations at the ground. When such calculations intensify or decay...

The SeaWinds scatterometer onboard the NASA QuikSCAT satellite has been providing forecasters in the Ocean Prediction Center (OPC) with Near-Real Time (NRT) ocean vector winds over large ocean areas since 1999. Although QuikSCAT's impact on the analysis and forecast process has been significant to the short-term wind warning process, this positive impact has not carried over to the analysis of the sea level pressure field over the open oceans. In an effort to improve their SLP analyses, OPC...

The overall goal of this effort was to use a hierarchy of process oriented numerical modeling studies to study the role played by a continuum of bottom bumps on flow over the continental shelf. Observed cross shelf currents over the shelf tend to have higher amplitudes and shorter length scales than can be accounted for by existing models. The approach here was to ask whether model experiments could produce realistic (in terms of amplitude and statistical quantities such as length scales) cross...

The main agricultural areas in South Florida are located within the fertile land surrounding Lake Okeechobee. The Atlantic Watershed monthly rainfall anomalies showed a weak but statistically significant correlation to the Oceanic Nino Index (ONI). No other watershed s anomalies showed significant correlations with ONI or the Southern Oscillation Index (SOI). During La Nina months, less sea breeze days and more disturbed days were found to occur compared to El Nino and neutral months. The...

This research is concerned with improving an existing algorithm to accurately forecast thunderstorm starting times for Cape Canaveral, Florida. This was accomplished by investigating different linear regression techniques than those used in the existing algorithm. The result is three new thunderstorm start time algorithms. The forecast start times of these new algorithms were then compared to actual thunderstorm start times to determine which method produced the most accurate results. The...

This study investigates the impact of the synoptic-scale flow on the propagation and intensity of the sea breeze front at Eglin Air Force Base. The 925 mb wind direction and speed from the 12 UTC Tallahassee sounding was used to categorize 509 summer days as having an offshore, onshore, or coast parallel synoptic-scale flow regimes. Days with similar synoptic-scale flows were then composite together to create hourly surface analyses for each regime. Sea breeze frontogenesis, location and...

The relationship between thunderstorm activity during the summer months along coastal regions of the Atlantic and Gulf coasts and the dry sea breeze circulation was investigated. Satellite composites of thunderstorm activity for synoptically undisturbed conditions have been obtained for south Florida for a series of days in the summer of 1983. These data were catalogued into different low level synoptic flow regimes. Five synoptic flow regimes were found from the data. A three-dimensional...

The source function and deposition velocity of sea-salt particles used in large-scale models assumes that the source and deposition is uniform over areas large compared to the horizontal grid spacing of the model, whereas sea-salt aerosol is overwhelmingly generated by white caps whose surface distribution is usually sparse and sporadic. The analysis presented here uses several puff plume models to study the validity of the underlying assumptions of the horizontally uniform surface source and...

The relatively shallow marine boundary layer adjacent to steep coastal topography along the California Coast give rise to a number of mesoscale phenomena, including coastally trapped disturbances (CTD's), expansion fans, land/sea breezes, low-level jets, and cyclonic eddies. CTD's occur several times each year during the period from May to early October and are easily distinguished in satellite imagery due to the distinctive narrow tongue of low clouds and fog propagating to the north along the...

The diurnal-period fluctuations of winds and surface currents are analyzed for September 1992 in and around Monterey Bay. Wind records are compared for three coastal stations and two mooring sites. Remotely-sensed surface current observations from two CODAR (HF radar) sites are used to explore the ocean's response to diurnal-period forcing. An average diurnal cycle is formed at each wind station and at all CODAR bins. The earliest sea breeze response is seen at the coastal wind stations where...

The results of a literature survey of weather-related effects on tropospheric radio propagation are summarized and presented in tabular form. Consideration of the available weather data, the prediction probability for various weather factors, and the limited knowledge of radio-weather relationships, leads to the conclusion that only very limited propagation predictions based on weather data are possible at present.
