Weather Forecasts

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.

  • What is the meaning of a red sunset?

    Q: What is the meaning of a red sunset?

    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.

  • How do low-pressure systems form?

    Q: How do low-pressure systems form?

    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.

  • What is the subpolar low polar front?

    Q: What is the subpolar low polar front?

    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

  • What causes the trade winds?

    Q: What causes the trade winds?

    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.

  • What factors affect weather?

    Q: What factors affect weather?

    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.

  • Q: What is the boundary between two air masses called?

    A: The boundary between two air masses is called a front. Fronts can be stationary, warm, occluded or cold and often affect the weather on Earth.

  • Where did Hurricane Ivan hit?

    Q: Where did Hurricane Ivan hit?

    A: In the United States, Hurricane Ivan impacted the area along the Gulf of Mexico, including Alabama, Florida, Louisiana and Texas. The effects of Hurricane Ivan reached as far north as Virginia and the Delaware River. Hurricanes: Science and Society indicates that Ivan finally dissipated over Texas.

  • Q: What is a weather front?

    A: A weather front is where two air masses meet. Depending on the type of air mass movement involved, fronts can be cold, warm, stationary or occluded. Each type of front produces a specific type of weather.

  • Q: What is the temperate climate zone?

    A: The temperate climate zone is located between the Tropic of Cancer and the Arctic Circle in the Northern Hemisphere and between the Tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere. Areas with a temperate climate generally have warm summers, cold winters and moderate springs and summers. They do not have extremes in temperature or precipitation.

  • Q: How does weather form?

    A: Weather forms primarily from conditions in the local atmosphere that change frequently over short periods of time. Weather, in the broadest sense, is the condition of the atmosphere in a set location that varies on a daily, weekly, or monthly basis. Weather is created by several different factors, such as temperature of the surrounding land and air, levels of humidity and type and volume of precipitation.

  • Q: What does the weather term "haze" mean?

    A: The weather term “haze” refers to pollution of salt, dust and fine particles that are dispersed through parts of a specific area’s atmosphere. Individually, these particles are invisible, but when grouped together, they form a haze that diminishes visibility.

  • How accurate are 15-day weather forecasts in Sarasota?

    Q: How accurate are 15-day weather forecasts in Sarasota?

    A: In 2013, meteorology students at Penn State University conducted a study of the accuracy of extended weather forecasts for fifteen American cities, reports the Washington Post. The results of the study indicate significant discrepancies between 15-day forecasts and actual temperatures. This would certainly apply to forecasts in Sarasota.

  • Q: What is a hurricane simulator?

    A: A hurricane simulator is a man-made device that replicates the weather conditions of a natural hurricane in a safely contained environment for study. They are comprised of a fan, water tank and wave generator. The simulator creates the conditions of a hurricane by using high-speed winds to mimic the weather disturbances researchers desire to observe.
