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 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: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: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: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: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 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:Twenty day weather forecasts are generally unreliable because weather has a tendency of being chaotic and unpredictable. According to Time and Date, the longer the weather forecast is, the less accurate it will be.
A:A weather report should engage the reader, present the current data, give bad news followed by good news and present the forecast. While a weather report cannot change the data, it can make the weather more interesting by adding anecdotes and other details.
A:Meteorologists use computer models to predict all forms of precipitation, including snow. These models rely on a single variable to determine if water is going to fall as rain, snow or ice. Once he predicts precipitation, the meteorologist compares the temperature forecast to determine the form of precipitation, such as snow.
A:The term "trade winds" refers to the regular winds that blow from the subtropical high pressure zones toward the equator in roughly westerly directions. They are so named on account of the way trading ships used these winds when sailing west from Europe to the Americas.
A:The maritime tropical air mass is the warm humidity often felt in the air in the southeastern part of the United States. It is the result of the combination of direct sunshine, the Gulf Stream and the Gulf of Mexico.
A:WTOL provides information related to school delays and closings during its news telecasts and on its website. The website has a special link for school closings accessible through the home icon on the far left of the home page's banner. The This Morning tab also includes a School Closings link.
A:Many meteorologists agree that there is little accuracy in weather forecasts that extend beyond seven days, so 30-day weather forecasts are not considered accurate. Oftentimes, a forecast extending beyond seven days is no more accurate than historical averages.
A:According to EarthSky, as of February 2, 2013, Punxsutawney Phil had made 117 predictions about the coming of spring and had only been correct 39 percent of the time. Phil has only predicted an early spring 16 times during that period.
A:Some good streaming services that show live winter weather forecasts include Weather.com, WeatherNationTV.com and Wunderground.com, as of 2015. The LiveWXRadar.com website provides users with streaming weather radar imaging worldwide.
