Alaska Climate Data - Wind. For the first order observing stations, detailed wind speed and direction data are available. These analyses are based on hourly observations for the period - Data are also available for Barter Island for the period - WEATHER OBSERVATIONS and TIDES. Latest 3 hr Coastal Observation (NOAA) Summary of buoy readings and local wind readings for Northern and Central CA as read on NOAA Weather Radio (includes Pillar Point). Fort Funston Wind Report Realtime wind speed, direction and temp on the cliff between Ocean Beach and Pacifica Pier (San Francisco). Updates. The Alaskan coastline bordering the Gulf of Alaska has steep coastal topography, as well as a variety of bays, straits, and sounds. The low-level flow frequently accelerates down the pressure gradient along the coast and out of coastal gaps to form complex three-dimensional coastal jets, which can be dangerous to the aviation and shipping industries. Similar super-geostrophic winds have been observed at coastal stations along Alaska (Businger and Walter, ; Reynolds, ). What is not known for these cases is how the storm system itself is modified by the presence of a coastline and orography. This interaction of storms and orography to produce coastal jets is a major area for research.

The previous assessment included data for two time periods, circas and circas. The update includes data from two additional time periods, circas and circas. The updated assessment confirms that Alaska’s north coast is dominantly erosional, with 84 percent showing shoreline retreat over the long term (s–s) and 77 percent over the short term.   At the moment, the storm is producing screaming 50 to 70 mph winds along the entire west coast of Alaska (according to a coastal flood warning posted by .   “These observations will provide an opportunity to closely study the role of coastal sea ice in dissipating wind-generated waves in the Arctic Ocean,” said co-principal investigator Nirnimesh Kumar, an assistant professor of civil and environmental engineering. “The ongoing reduction in seasonal ice cover in the Arctic Ocean may cause. Coastal upwelling along the central-northern coast of Chile is intensified around a few large headlands, such as Punta Lengua de Vaca (30° S) and Punta Curaumilla (33° S), and is driven by south-southwesterly winds events during austral spring and summer.

Coastal winds in autumn and early winter are generally southeast, then shift to south-southwestby late winter. Figure 3 shows representative surface wind stress vectors for June and December (Nelson, ). These wind stress fields are based on historical surface marine wind observations and illustrate the seasonal variability of the coastal. Alaska - Alaska - Climate: Alaska is known for its variable climate, which is influenced by ocean currents. The western coasts are bathed by the Alaska Current, which carries relatively warm Pacific waters northward and westward along the southern Aleutian Islands. Those warm oceanic waters enter the Bering Sea and then flow eastward along the northern coast of the Aleutians. during the Coastal Observations and Simulations with Topography experiment. This section of coastline constitutes a steep, approximately two-dimensional north–south-oriented orographic barrier. The front exhibited a northeast–southwest orientation and thus intersected the axis of high terrain at an acute angle. The along-. Email this Article Chinook winds.

1. Introduction. The northern Gulf of Alaska (GOA) is an ecosystem dominated by advection, with the well-defined Alaska Coastal Current (ACC) transporting ~1×10 6 m 3 s −1 anti-clockwise along the coast (Royer,Stabeno et al.,Weingartner et al., ).The ACC is driven by along-shore winds, with a hydrographic signature that is characterized by a low salinity core.

The SAR image shows strong surface winds both north and south of Kodiak Island blowing from the Alaska Peninsula. A ship observation at UTC 22 September from the Tustumena at °N and °W confirms that the surface winds at the northern tip of Kodiak were 37 kt ( m s −1) in good agreement with the SAR image.

Operational wind products are produced from SAR, for example, by the National SAR Wind Program in Canada (Khurshid et al. ) and by the Alaska Coastal SAR Program in the United States (Monaldo.

Lower SST values are observed, as a result of coastal shoaling of the thermocline off the Gulf of Papagayo, forced by Ekman pumping on the equator side of the Papagayo wind jet. Upwelling of low-temperature and nutrient-rich waters promotes phytoplankton growth and Chl a accumulation.

Lindsay et al., show NCEP winds to be well correlated (r ~) with high Arctic (>80°N) in situ wind observations (Soviet ice‐camp measurements from to ), and prior Bering Strait wind‐to‐water‐flow correlations with NCEP winds are comparable to results using other wind products (JRA‐25, Wind is a climate variable with major impacts on humans, ecosystems and infrastructure, especially in coastal regions with cold climates.

Climate-related changes in high-wind events therefore have major implications for high-latitude residents, yet there has heretofore been no systematic evaluation of such changes in a framework spanning historical and future timeframes.

In coastal regions, wind ellipses are expected to be roughly perpendicular to the coastline, with the exact orientation predicted to depend on several factors including latitude and friction (3,12). However, topography can steer the winds, so for example, along the west coast of South America, wind ellipses are oriented parallel to the Andes.

With the steering of the wind into the centre of the low, plus the added frictional effects of the land we'll see south-west winds at the coastal interface, but more inland they'll swing even more westerly in direction.
