Breeze Wind Power In China

wang, zhong tao, liu, qian January 2012 (has links)
China is an energy production and consumption country, wind power is one of the greatest development potential energy.The authors use literature research methodology, case study, comparative study and trend analysis study to analysis current condition of the breeze wind power.China has a long history of wind development, use wind power to generate electric is only developed in recent years, but it is expanding fast. China is a country covering vast territory, and it is rich in wind resources. But some reasons such like natural, economy, environmental etc, limit the wind power development of China.The VAWT is a new kind of wind driven generator, it has many advantages that HAWT doesn’t have. Utilize VAWT to develop breeze wind power generation, will bring wind power into more families.

Defining Environmental Characteristics of Sea Breezes along the U.S. Gulf Coast

Maldonado Jaime, Janice 15 August 2014 (has links)
Studies of sea breeze have been done on coastline locations worldwide, but only a few have focused on the U.S. Gulf Coast. This area is frequently influenced by sea breeze events; therefore, it is important for meteorologists to determine where and when these systems will occur. The objectives of this study are to quantify sea breeze frequency along the Gulf Coast and define the associated environmental characteristics. The study is based on sea breeze development during synoptically benign days. From 1991 to 2010 a total of 1,255 days were classified as synoptically benign, with 161 of those days identified as a sea breeze day through analysis of clouds from Geostationary Operational Environmental Satellite (GOES) imagery. The average surface temperature was significantly different between sea breeze and non sea breeze days, but the average surface wind speed and direction were not significantly different making them poor descriptors of sea breeze environments.

An examination of lake breezes in southern Manitoba

Curry, Michelle 01 1900 (has links)
Lakes represent a major topographic feature in southern Manitoba, having a direct meteorological influence on a number of communities, including Winnipeg. Therefore, it is crucial that we have an understanding of the characteristics of lake breezes in the region and the influence that they can have on local weather. The Effects of Lake Breezes on Weather in Manitoba (ELBOW-MB) project in 2013 sought to fill in the gaps in our current knowledge of lake breezes in southern Manitoba. The primary research objectives of this thesis are to: (1) provide a radar-based climatology of lake breeze frequency and characteristics and, (2) to characterize the detailed thermodynamic and kinematic properties of lake breezes and lake-breeze fronts. The two results papers presented within this thesis represent the first detailed analysis of lake breezes in southern Manitoba and help to fill important gaps in our knowledge about the occurrence and characteristics of lake-breeze circulations. / February 2016

The impact of synoptic-scale flow on sea breeze front propagation and intensity at Eglin Air Force Base

Weaver, James C. 03 1900 (has links)
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 composited together to create hourly surface analyses for each regime. Sea breeze frontogenesis, location and intensity were analyzed on hourly plots of temperature, winds and frontogenesis. Results indicate that the most intense sea breeze fronts formed under 3-5 1 ms- offshore, 7-9 1 ms- coast parallel easterly, and 3-5 1 ms- coast parallel westerly synoptic-scale flow while the weakest fronts formed under 0-3 1 ms- onshore and coast parallel westerly flow. The inland penetration of the sea breeze front was restricted under offshore flow but propagated through the Eglin Range Complex under onshore flow. The intensity of the sea breeze front was found to be a balance between convergence (frontogenetic) and turbulent mixing (frontolytic). Under onshore flow the sea breeze front formed late in the afternoon when convergence at the front was maximized and turbulent mixing decreased. Under offshore flow, the strongest sea breeze fronts formed early in the afternoon due to strong convergence between offshore and onshore winds and weak turbulent mixing.

An investigation of diurnal variability in wind and ocean currents off Huntington Beach, California

Taylor, Kelly E. 03 1900 (has links)
Approved for public release; distribution unlimited / In conjunction with the Huntington Beach Phase III Investigation, the diurnal variability in the wind and ocean currents from July 1 - October 12, 2001 over the San Pedro Shelf is investigated. Results suggest that the diurnal currents are driven by the diurnal winds but that the strength of the ocean response is modulated by the low frequency flow regime. The spectral peak of the near-surface currents is at the diurnal frequency, which is below the inertial frequency (1.107 cpd). The diurnal currents are surface-intensified, decaying with depth to a minimum at 10-13 m and increasing slightly in strength below that. The near-surface diurnal currents are in phase across the shelf, and are close to in phase with the winds over the shelf. The amplitude modulation of the diurnal energy of the ocean currents is correlated with the direction of the low frequency flow along the shelf;the energy is enhanced when the flow is equatorward, and weak when the flow is poleward. The amplitudes of the diurnal near-surface currents are also correlated with the diurnal winds. However, the low frequency currents and winds are not well correlated. / Lieutenant, United States Navy
