The two main factors that determine climate are temperature and the amount of precipitation an area gets. The climate of an area is determined over a long period of time, generally more than a lifetime.
A:The amount of sunlight striking an area, the geographic location of an area, the air pressure surrounding an area and the amount of water in the atmosphere all influence the local weather. Each of these components interacts with the other components, and they may exacerbate or moderate each other.
A:The sun appears red at night because the light it emits must travel a farther distance. Most of the shorter wavelengths have already scattered upon hitting particles in the air, and the only wavelengths left to view are the longer red wavelengths.
A:The trade winds are caused by a combination of convection air currents and the Earth's rotation. Air is warmed near the Equator and moves towards each pole, respectively. This air is deflected by the Coriolis effect, or the spin of the Earth, causing it to fall back towards the Equator in both hemispheres.
A:A subpolar low front is a low pressure system that is small and fleeting. Subpolar lows are typically found over the ocean, near the primary polar fronts at the poles of the northern and southern hemisphere. In the northern hemisphere, the polar front created produces low pressure cyclonic storms in Europe and the Pacific Northwest. In the Southern Hemisphere, it creates severe storms, high winds, and snowfall in Antarctica
A:According to About.com, areas of low pressure within the Earth's atmosphere are caused by unequal heating across the surface and the pressure gradient force. Incoming solar radiation largely concentrates at the equator, resulting in warmer air at the lower latitudes. This warm air has a lower barometric pressure than the cooler, denser air near the poles, and the differences between these types of air create the pressure gradient force.
A:The weather of any given region is important because it has a considerable impact on the water, sunlight and temperature of an ecosystem, according to the University of Illinois. These factors play a serious role by influencing the types of plant and animal wildlife that can survive in the area. Certain weather patterns can also cause dangerous storms and natural disasters.
A:Due to British Columbia's size and diverse topography, the climate varies significantly from one area to another. The province has a marine climate on the coast and a continental climate in the interior. Its proximity to the Pacific Ocean, northern latitude, mountainous landscape, north-south oriented mountain ranges and prevailing westerly winds affect its climate.
A:Fall color forecasts for Michigan are available on sites devoted to foliage, such as FoliageNetwork.com, local and national sites with interactive maps and weather sites. FoliageNetwork.com has weekly foliage reports throughout the fall season that break down the country into various regions.
A:A meteorologist uses satellite imagery, air observations and computer models to predict thunderstorms. According to The Weather Channel, thunderstorm forecasting is very similar to the forecasting used to predict tornadoes.
A:The United States National Weather Service and the Meteorological Service of Canada provide detailed marine forecasts for Lake Erie. Both agencies provide forecasts for different regions of the lake, including the waters of the other country.
A:National Weather Service meteorologists measure snowfall by studying radar intensities during winter storms, and more traditional measurements of snowfall rates involve taking ground measurements several times per hour. The more intensely the snow echoes on radar, the faster the rate of snowfall. Lighter radar intensities indicate slower rates. Standard radar images correlate to snowfall rates during a storm based on the intensity and duration of snowfall over a given area.
A:To view a live local Doppler radar map, go to the National Weather Service enhanced radar image website at Radar.weather.gov, and click on the radar site nearest you. Click on the map to create a more precisely targeted selected location. Menu items on the left display information such as the velocity of a storm or rainfall projections relative to the selected location. The map displays information in colors with a corresponding legend in the lower right corner.
A:The weather in St. Lucia in November ranges in temperature from a low of 79 degrees Fahrenheit to a high of 84 degrees Fahrenheit, with an average of 18 days during the month seeing some rainfall. During November, the rainy season begins to end, and dry season starts.
A:Some types of weather maps are temperature, wind, pressure, radar, jet stream, satellite and front maps. These different weather maps provide information on the prevailing meteorological conditions of a specific location. For example, a temperature map can include the variation in temperatures either on a global scale or confined to a smaller sector, such as a particular city or country.
A:A falling barometer reading usually indicates that a storm or wet weather is approaching. A more rapid change indicates the weather will change sooner. A barometer reading that remains steady indicates that no immediate change in weather should be expected.
A:Because weather is often unpredictable and directly affects the conditions following it, 10-day weather forecasts may or may not be accurate. Short-range forecast predictions, defined as those up to 48 or 72 hours from the present, are generally much more accurate than those of longer periods.
A:The first signs of an approaching warm front include a general movement of air from southwest to northeast, a drop in air pressure, and warmer air found behind the movement of the front. Warm fronts tend to signal a general change in weather.
A:Meteorologists study the earth's atmospheric phenomena (primarily weather and climate) and the effects that these phenomena have on other environmental processes. Meteorologists use this information to predict weather patterns and also to focus on the relationship and impacts that the weather has on the lives of humans.
A:Local wind patterns may be obtained from the local TV weather forecast. Because wind patterns change frequently, these weather broadcasts are often daily. Some examples of local winds include sea and land breezes.
