Book Description
During the 1972 IFYGL 'alert' periods, the highly instrumented NOAA/RFF/DC-6 aircraft was used to record the time series of wind, temperature, and water vapor at heights ranging from 18 to 300 m above the surface of Lake Ontario. The aircraft was equipped with a gust probe system, a fast response thermistor, a microwave refractometer (for water vapor measurements), and a downward-pointing IR system; as well as the normal in-flight measurement of standard meteorological parameters. The time series records have been found to display a highly intermittent nature. This is especially the case for evaporation when, in the fall, Polar Continental outbreaks move across the lake. In particular, such an outbreak of cold dry air moved across the lake at 12-15 m s−1 on 9 October 1972. This resulted in the air temperature at 30 m above the lake to drop from 12 to 6 C while the evaporation rate increased to more than 1 cm day−1. This may be compared with the 0.5 cm day−1 normal evaporation observed in the tropics during BOMEX. Furthermore, IR lake surface temperatures show cold regions (~5 C) along the north shore, presumably due to strong upwelling, while the center and south shore regions of the lake were of the order of 12 to 15C. The turbulent, flux quantities of momentum, heat, and water vapor were obtained by the eddy correlation technique and their spectra were determined at several locations over the lake surface for 3-minute sampling lengths. At the aircraft speed of 92 m s−1, this represents a flight path of ~17 km for both along wind and constant fetch patterns. The spectra demonstrate the tendency for the peak value to march to higher wavelengths with increasing height.

Influence of Earth Surface and Cloud Properties on the South Florida Sea Breeze
Author: Patrick T. GannonPublisher:
ISBN:
Category : Sea breeze
Languages : en
Pages : 100
Book Description
A two-dimensional numerical sea breeze model that includes radiation and heat budget physics is used to study sea breeze circulations affected by South Florida surface and cloud conditions. Sensitivity experiments show major differences in the intensities and inland penetrations that result from prescribed distributions of surface and cirrus cloud properties. A case study experiment for July 16, 1975, provides a measure of the importance of surface and cumulus cloud properties that were observed or deduced for this one day. Significant differences exist between the model version using a surface heat budget formulation and the version using prescribed thermal forcing. The strength of the sea breeze predicted with the heat budget formulation decreases with increasing initial basic state wind speeds, while the opposite effect occurs with thermal forcing. Soil moisture is the dominant controlling surface property, followed by albedo and thermal inertia. Cirrus clouds can prevent the evolution of the sea breeze when the geometric thickness of cirrus exceeds 2 km. A case study demonstrates the importance of cumulus cloud shielding of the surface from solar radiation. The mesoscale sea breeze convergence zone is seen to evolve adjacent to organized cloud fields, but not necessarily coincident with them. This is an important consideration when sea breeze models are verified with observed cloud fields.
