“…The variation in the wind direction in Ahtopol: between 9:00 LT and 11:00 LT changed from WS to NE. This change was due to the breeze (Kolev et al 1998), after 12:30 LT the wind direction was SE.…”

“…Measurements of the sea breeze using ground-based lidar include the work of Nakane and Sasano (1986), documenting the shape and turbulent structure of the sea-breeze front on the Kanto Plain of Japan (ϳ60 km NE of Tokyo) using an aerosol lidar. Kolev et al (1998) deployed a groundbased aerosol lidar on the shore of the Black Sea, paired with pilot balloon measurements, capturing the transition from offshore to onshore flow. Other studies used ground-based lidar to assess the influence of the sea breeze on the properties of aerosols in coastal regions, including that of Kolev et al (2000), Murayama et al (1999), and Vijayakumar et al (1998).…”

A NOAA/Environmental Technology Laboratory Doppler lidar measured the life cycle of the land-and seabreeze system at Monterey Bay, California, in 1987, during the Land-Sea Breeze Experiment (LASBEX). On days with offshore synoptic flow, the transition to onshore flow (the sea breeze) was a distinct process easily detected by lidar. Finescale lidar measurements showed the reversal from offshore to onshore flow near the coast, its gradual vertical and horizontal expansion, and a dual structure to the sea-breeze flow in its early formative stages. Initially, a shallow (Ͻ500 m) sea breeze formed that later became embedded in a weaker onshore flow that was ϳ1 km deep. Eventually these two flows blended together to form a mature sea breeze about 1 km deep.Regional Atmospheric Modeling System (RAMS) two-dimensional simulations successfully simulated this dual structure of the sea-breeze flow when both the coastal mountain range just east of Monterey Bay and the Sierra Nevada range, peaking 300 km east of the shore, were included in the domain. Various sensitivity simulations were conducted to isolate the roles played by the land-water contrast, the coastal mountain range, and the Sierra Nevada range. Notable results included the following: 1) the Sierra Nevada range greatly affected the winds above 1500 m at the shore, even though the peak of the mountain range was 300 km east of the shore; 2) the winds at the shore, below 1500 m, were most affected by the land-sea contrast and the coastal mountain range; and 3) the presence of the coastal mountain range enhanced the depth of the sea-breeze flow but not necessarily its speed.A factor separation method was employed to further isolate the contributions of the terrain and land-water contrast to the vertical structure of the modeled u component of the wind. When both mountains were included in the domain, the interaction of the slope flows generated by these mountains acted to strongly enhance onshore flow early in the morning. In contrast, the interaction of flows generated by the land-water contrast and the sloping terrain had its strongest effect late in the afternoon and early evening, working to oppose the sea-breeze flow. The triple interaction of the flows generated by the coastal mountain, inland mountain, and the land-water contrast enhanced the sea-breeze flow from the surface to 500 m above the sea level throughout the day.well to analytical and numerical modeling. However, many components of the sea breeze have been difficult for researchers to measure in detail, such as the vertical and horizontal structure of the winds over the water. Other complicating factors include the effects of inland topography; for example, inland mountain ranges generate their own thermally forced slope flows, which interact with the sea breeze. Along the coast of central California the diurnal flow behavior is driven by the land-sea contrast and two ranges of mountains. The following is a study of these interactions.The development of clear-air remote sensing instrumentation has allo...

“…It should be noted that using (6) we can define a large scale correlation time t. From the condition A(a, r) 0, for T > t we derive that the expression for the large correlation time within the considered model is given by: tc = (a -1)k;' (8) The practical importance of approximate self-affinity rest on: (i) it is this symmetry, that seems to be encountered in the nature rather than the exact self-affinity; (ii) unlike the exact self-affinity, using the approximate one allows to obtain finite statistical quantities and on this basis to construct pertinent models of various natural phenomena and structures. In the next section we employ one such model, namely for the autocovariance function, introduced l)y equation (3), to characterize the lidar data.…”
