The westerlies explain why coastal Western North America tends to be wet, especially from Northern Washington to Alaska, during the winter. The strength of the sea breeze is directly proportional to the temperature difference between the land mass and the sea. About the Science. Climate Auckland. Like trade winds and unlike the westerlies, these prevailing winds blow from the east to the west, and are often weak and irregular. frost days, Climate Current Heat Index. As with massing, orientation for thermal comfort is similar to orientation for daylighting, with some exceptions: First, the amount of sunlight that is optimal for daylighting is often not optimal for solar heat gain. These are winds that drive the system of surface currents in the ocean. But like anything (except for donuts, obviously), the city also has a couple of drawbacks. Birkdale, Ormiston, Thorneside and Wellington Point. the prevailing winds are named for the direction from which they are coming. The westerlies can be particularly strong, especially in the southern hemisphere, where there is less land in the middle latitudes to cause the flow pattern to amplify, which slows the winds down.

The wind is most often from the south for 3.1 months, from May 2 to August 4, with a peak percentage of 39% on June 3. The most favorable orientations occur where the amount of incident radiation in winter is greater than that incident in summer, where the blue line extends out beyond the red line. The following points summarise some aspects of wind measurement undertaken by the Bureau of Meteorology. We provide archived past measurements from this and many other weather stations. [24], Orographic precipitation occurs on the windward side of mountains and is caused by the rising air motion of a large-scale flow of moist air across the mountain ridge, resulting in adiabatic cooling and condensation. Orientation is simply what compass direction the building faces. This orientation lets you consistently harness daylight and control glare along the long faces of the building. For example, the prevailing winds in Canada come from the west. Wind roses are tools used to display the direction of the prevailing wind. Download variables such as temperature, wind .

The Brisbane Airport Master Plan 2003 contained a comparison of various options. [9][10] These prevailing winds blow from the west to the east,[11] and steer extra-tropical cyclones in this general direction. The extension of the cross-runway is Option 5. Additional city names appear when the user zooms in on the map. Solar heat gain on the east side can be acceptable or even useful, because it happens in the morning after the cooler night; but solar heat gain on the west side is rarely desirable at the end of an already warm day. Prevailing winds are the predominant surface winds in an area. The air that comes in contact with the warmed slopes becomes warmer and less dense and flows uphill. Prevailing winds move in one direction. The cooler air above the sea, now with higher sea level pressure, flows towards the land into the lower pressure, creating a cooler breeze near the coast. Prevailing winds are from the southwest, except in winter when west to northwest winds dominate. New Zealand's prevailing winds come from the west, and the country sits just north of the extreme westerlies further south. The best way to determine the direction of prevailing winds at your home or business is to document the wind direction each day for a .

Interactive wind speed map. Tree limbs can break and driving gets white-knucklecars can veer off the road. [18] The sea therefore has a greater capacity for absorbing heat than the land, so the surface of the sea warms up more slowly than the land's surface. This graph shows how thermal heat gain on the east and west sides of buildings change rapidly as the sun moves through the day, while northern and southern exposures are more consistent. Because of this, wind barrier strips have been developed to minimize this type of erosion. If the temperature onshore cools below the temperature offshore, the pressure over the water will be lower than that of the land, establishing a land breeze, as long as an onshore wind is not strong enough to oppose it. You can also order the raw wind and weather data on our historical weather data request page (for example for an insurance case, to better plan your vacation etc). percentages, Rainfall The wind roses at MO MSU in both 2017 and 2018 spring seasons show the relatively homogeneous distribution of the wind direction during the sampling period, with the prevailing south-west . The wind is most often from the east for 10 months, from August 14 to June 20, with a peak percentage of 65% on January 1. between 35 and 65 degrees latitude), which blow in areas poleward of the high pressure area known as the subtropical ridge in the horse latitudes. Wayne Baddock says his radar islocated on top of a hill in the seaside town of Gracetown, Western Australia, and isable to pick up current temperatures, wind speeds and rainfall. The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds - the trade winds - to move from east to west on both sides of the equator across this 60-degree "belt.".
