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 are the two main factors that determine climate?

    Q: What are the two main factors that determine climate?

    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 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 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.

  • 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.

  • 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.

  • Q: How do you interpret a frost map?

    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.

  • Q: Does the National Weather Service provide rain totals by ZIP code?

    A: The National Weather Service, in conjunction with the National Oceanic and Atmospheric Administration, provides a historical precipitation report that is categorized by ZIP code. This database does not list rainfall totals for each ZIP code individually, but it offers a search option instead.

  • Q: Why is temperature important?

    A: Temperature is a major determining factor of global climate patterns. It affects the life cycles of plants and animals, influences weather and tides, and controls the freeze and thaw of the polar ice caps. A small change in average temperature can have powerful effects on the environment worldwide.

  • Q: What is the average temperature on the equator?

    A: The average temperature on the equator is usually between 18 and 27 degrees Celsius. This is much hotter than the average temperatures around the Earth because the equator receives the most direct sunlight. This average takes into account temperatures during both the day and night.

  • What are the six elements of weather?

    Q: What are the six elements of weather?

    A: The six basic elements of weather include temperature, humidity, atmospheric pressure, wind, precipitation and cloudiness. When combined, these elements can describe the weather conditions extant.

  • Q: How does an anemometer work?

    A: An anemometer measures the wind speed through the use of a vertical shaft that is attached to a device displaying the wind speed. It is composed of three or more metal cups connected to the edge of horizontal arms placed on a shaft.

  • Q: How do you explain the relationship between fronts and low pressure systems?

    A: A front is a boundary between air masses that leads to a low pressure system as the atmosphere attempts to even out the temperature contrast. If there is enough moisture in the air, the uplift as these two air masses collide causes rain. If the temperature differential is large enough, the collision leads to thunderstorms, according to NOAA.

  • Do the previous 10 days' weather reports help meteorologists predict future weather?

    Q: Do the previous 10 days' weather reports help meteorologists predict future weather?

    A: Knowing the recent weather from previous days is where most meteorologists start their predictions. By knowing where weather systems were and how they were moving, meteorologists are able to predict where a system will go, and how it will interact with other weather systems.

  • Q: How do you view a live local Doppler radar?

    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.

  • Q: How are climate and weather related?

    A: Climate and weather both describe atmospheric conditions. Weather describes short-term occurrence of conditions in the atmosphere, while climate refers to long-term weather patterns over a specific time frame. Weather changes on a daily basis, but climate extends over a long period of time.

  • Q: What is the climate in British Columbia?

    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.
