In meteorology, the barometric pressures shown are reduced to sea level, not the surface pressures at the map locations. The distribution of isobars is...

Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study...

elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure...

In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more...

pressures that occur above 40,000 feet (12 km). The lines of equal air pressure are called isobars. Isotherms are the lines of equal air temperature. v t e...

In the context of meteorology, a solenoid is a tube-shaped region in the atmosphere where isobaric (constant pressure) and isopycnal (constant density)...

type of surface weather map is the surface weather analysis, which plots isobars to depict areas of high pressure and low pressure. Cloud codes are translated...

geostrophic (parallel to the isobars), while within the PBL the wind is affected by surface drag and turns across the isobars (see Ekman layer for more detail)...

realistic. In meteorology, a barotropic atmosphere is one that for which the density of the air depends only on pressure, as a result isobaric surfaces (constant-pressure...

A col, also called saddle point or neutral point, is in meteorology, the point of intersection of a trough and a ridge in the pressure pattern of a weather...

countless other implications. Wind direction is usually almost parallel to isobars (and not perpendicular, as one might expect), due to Earth's rotation....

Blocks in meteorology are large-scale patterns in the atmospheric pressure field that are nearly stationary, effectively "blocking" or redirecting migratory...

height. However, if a horizontal temperature gradient exists along isobars, the isobars will also vary with the temperature. In the mid-latitudes there often...

gradient is visible in isotherms and can sometimes also be identified using isobars since cold fronts often align with a surface trough. On weather maps, the...

{\displaystyle p} = pressure [Pa]. In meteorology, p 1 {\displaystyle p_{1}} and p 2 {\displaystyle p_{2}} are isobaric surfaces. In radiosonde observation...

can be represented in two ways: On surface weather maps, the pressure isobars form contours where the maximum pressure is found along the axis of the...

presentations, explaining complicated meteorological concepts in layman's terms where needed and enhancing charts with isobars and upper-level diagrams. This...

force and deflecting force that in the end causes air masses to move along isobars was understood. In Newtonian mechanics, the equation of motion for an object...

saturated water vapor with horizontal isobars. As the pressure is a function of temperature alone, the isobars are also isotherms. If the process involves...

high-pressure centers are identified by the letter H in English, within the isobar with the highest pressure value. On constant pressure upper level charts...

high-pressure centers are associated with the letter H in English, within the isobar with the highest pressure value. On constant-pressure upper-level charts...

(also known as geostrophy). The geostrophic wind is directed parallel to isobars (lines of constant pressure at a given height). This balance seldom holds...
