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 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: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 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 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: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:To get the 10-day weather forecast for Chicago, go to weather.com, timeanddate.com or accuweather.com. On the home page of weather.com, enter "Chicago" in the search box, and on the AccuWeather page, enter "Chicago" in the box marked Accuweather For. On timeanddate.com, scroll down to Weather, and type in "Chicago."
A:The temperature humidity wind index, or THW, determines what the temperature actually feels like based on the heat index and wind chill combined. For example, the temperature could be 50 degrees Fahrenheit, but due to high wind chill and heat index factors, the THW determines it feels like 40 F.
A:Normal barometric pressure is typically around 101.325 kPa / 1013.25 mbar / 760 mmHg / 29/921 inHg. Pressure rarely increases or decreases more than 1 inch of mercury (3.386 kPa / 33.86 mbar / 25mmHg) above or below the 30-inch mark unless the weather conditions are extreme.
A:Only two official weather-related terms begin with the letter Q: quasi-stationary front and quantitative precipitation forecast. Some less technical words beginning with Q can apply to weather as well; for example, a storm can move quickly, and scientists can measure quantities of rain or snow.
A:To interpret a frost map, look at the map's title to determine whether it shows the first or last frost. Find your location on the map, and identify the color that covers your location. Locate the corresponding color in the map key, and look at the date range to see when the frost happened in your area.
A:On September 24, 2005, at 2:40 a.m. Central Time, Hurricane Rita made landfall between Johnson Bayou and Sabine Pass in extreme southwestern Louisiana. Rita was a Category 3 storm when it made landfall. It caused over $12 billion in damage and over 100 fatalities.
A:A hurricane alert is a public statement by meteorologists that provides information about a hurricane that is expected to occur in the near future. Hurricane alerts include both watches and warnings.
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:Some resources for long-range weather forecasts include the Farmer's Almanac, the Weather Underground and the National Weather Service. These services also include past weather data as well as discussions of past and ongoing climate change.
