“Station pressure” is the air pressure at a reporting location, measured using a barometer. Altitude and temperature affect readings, and weather patterns can be predicted by changes in pressure. Readings are reported in inches of mercury or hectopascals. “Station pressure” is a term used in meteorology that describes the air pressure at the reporting location. […]
Saturation occurs when air holds as much moisture as possible, resulting in a relative humidity of 100%. Temperature and pressure affect the amount of moisture air can hold, with warm air holding more. Saturation leads to dew and precipitation, and is measured by relative humidity and dew point. Rising warm air cools and becomes more […]
Present weather is the atmospheric condition at a given moment, affected by solar radiation and the Earth’s tilt. The jet stream and small atmospheric changes can impact weather globally. Other planets also experience weather changes, with Venus and Jupiter having notable phenomena. The present weather is the condition of atmospheric phenomena occurring at a given […]
Snowpack refers to snow deposits on the earth’s surface, which can be permanent or seasonal. Meteorologists use snow cover levels to monitor environmental health and aid forecasting. Satellites can collect data on snowpack, which can be analyzed to create comprehensive maps. Snow can indicate climate change and provide a source of water, so water management […]
Air masses are large volumes of air with uniform temperature and moisture content, classified by their temperature and area of origin. Continental air masses are dry, while maritime air masses are moist. Air masses move based on temperature and density, creating air fronts that cause meteorological phenomena. Factors such as volcanic eruptions and melting polar […]
Marine smoke is caused by warm air rising through cold air above the surface of the water, creating plumes of gray or white smoke. It dissipates quickly and rarely poses a serious hazard, but can reduce visibility for vessels. It is often found in the North Atlantic Ocean. Marine smoke is a weather event caused […]
Isobars are lines connecting points of equal atmospheric pressure on a weather map. By plotting isobars, meteorologists can predict weather, wind strength and direction, and temperatures. Pressure readings are taken at weather stations and adjusted to sea level values. Low-pressure areas bring clouds and precipitation, while high-pressure areas bring clear weather. Wind flows from areas […]
Isotherms are contour lines on a weather map that connect points with equal temperatures. They show temperature gradients and are affected by factors such as elevation, water bodies, and latitude. The 32°F isotherm is important for predicting precipitation. Temperature advection occurs when winds blow across the isothermal gradient, causing extreme weather. In meteorology, the term […]
Meteorology courses are available at universities and colleges, with degree programs covering topics such as climatology and physical meteorology. Short-term courses are also offered for TV and radio weather presenters. Some employers have in-house meteorologists who provide training for new presenters. Non-profit groups and government agencies also offer courses for amateur enthusiasts and school children. […]
