What are the lines on a weather map that connect places of equal pressure called Question 9 options isobars contour lines pressure gradient forces isotherms?
Isobars and isotherm are both lines joining places on a weather map. Isobars join places with equal air pressure, and isotherms join places with equal temperature.
What are the lines on a air pressure map called?
The Isobars Those plain lines that curve across the map are called isobars (iso = equal, bar = pressure). They join together places with the same mean sea level air pressure (weight per square area of air above).
What are the lines on the weather map called?
Isobars are the plain lines curving across the map. They connect points with the same mean sea level air pressure (weight per square area of air above). Some isobars have numbers on them showing this value in hectopascals (hPa). Isobars indicate the flow of air around weather systems.
What are lines that connect all places where pressure is the same?
Isolines are the lines drawn to connect different places which share a common feature. Isobars are the lines on a map joining the places with the same atmospheric pressure. Isobar are commonly used in television for the weather forecast.
What are the lines on a weather map that connect places of equal pressure called quizlet?
A line connecting points of equal pressure on a weather map is called an isobar.
What is isobar line?
Isobar (meteorology), a line connecting points of equal atmospheric pressure reduced to sea level on the maps. Isobaric process, a process taking place at constant pressure.
What is an isobar line?
Isobars are lines of constant or equal pressure on a weather map. They can be used to find areas of low or high pressure over a broad area (like the U.S.), and they can tell us how intense the system may be.
What is isotherms and isobars?
Hint: Isobars and isotherms are lines or contours on a map that join points having the same pressure and temperature respectively. Isobars and isotherms have varied purposes especially in the fields of thermodynamics and geography.
What is a weather trough and ridge?
Ridges and troughs are often mentioned on the weather forecast. A ridge is an elongated area of relatively high pressure extending from the center of a high-pressure region. A trough is an elongated area of relatively low pressure extending from the center of a region of low pressure.
What is a isobar and isotherm?
Isobars and isotherms are lines on weather maps which represent patterns of pressure and temperature, respectively. They show how temperature and pressure are changing over space and so help describe the large-scale weather patterns across a region in the map.
What are contour lines?
A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line.
What type of lines on a temperature map connect points of equal temperature?
A broad term for any line on a weather map connecting points with equal values of a particular atmospheric variable (temperature, dew point, etc.). Isotherms, isotachs, etc. are all examples of isopleths. These are lines of equal wind speed.
What is a line on a weather map that separates areas of equal air temperature?
Isotherm. A line representing points of equal temperature.
What is an isobar that connects points of equal pressure called?
Isobars: lines of constant pressure. A line drawn on a weather map connecting points of equal pressure is called an "isobar". Isobars are generated from mean sea-level pressure reports and are given in millibars. The diagram below depicts a pair of sample isobars.
What are lines of equal temperature called?
Isotherm: lines of equal temperature in air or sea.
What are isotherm lines?
Temperatures and Temperature Analyses Isotherms (map on right) are red lines which connect equal temperature values based on the set from 0 °F with an interval of 10 F° above or below that. Isotherm values are labeled in red within the isotherm lines that are contained in the map area.
What is ridge and col?
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 map. It takes the form of a saddle where the air pressure is relatively higher than that of the low-pressure regions, but lower than that of the anticyclonic zones.
What is a ridge on a weather map?
Ridges and troughs are often mentioned on the weather forecast. A ridge is an elongated area of relatively high pressure extending from the center of a high-pressure region. A trough is an elongated area of relatively low pressure extending from the center of a region of low pressure.
What is an isobaric map?
Isobars are lines showing points of equal air pressure on a map. An isobaric map is analogous to a topographic map, where, on a topo map, lines represent points of equal elevation. An isobaric interval is chosen depending on how many isobar lines are desired.
What are isobars and isochore?
Isobars – Isobars are the elements having same mass number but different atomic number. Isochors – The line which is plotted in pressure vs temperature graph; at constant volume are called isochors.
What is an index line?
Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. This tells you the elevation above sea level. 2. Intermediate lines are the thinner, more common, lines between the index lines.
What is a supplementary line on a map?
Supplementary contour lines are placed between regular contour lines to visualize small but important forms that regular contour lines are unable to show. On topographic maps, typical forms are hillcrests, depressions, saddles, terraces, banks, and levees.
What are lines joining places of equal temperature?
Isotherm: lines of equal temperature in air or sea.
What are lines of equal elevation called?
contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. The diagram illustrates how contour lines show relief by joining points of equal elevation.
What are Isohyets and isobars?
Isobars are lines on a map showing places of equal pressure. Isotherms are lines on a map showing places of equal temperature. Isohels are lines on a map showing places of equal sunshine. Isohyets are lines on a map showing places of equal rainfall.
What is isotherm and isobar?
Hint: Isobars and isotherms are lines or contours on a map that join points having the same pressure and temperature respectively. Isobars and isotherms have varied purposes especially in the fields of thermodynamics and geography.
What is a trough line?
A line along which pressures are lower than in the surroundings and where the cyclonic curvature of the isobars is a maximum.
What are isobars in weather?
Isobars are lines of constant or equal pressure on a weather map. They can be used to find areas of low or high pressure over a broad area (like the U.S.), and they can tell us how intense the system may be.
What is a trough line weather?
A trough is an elongated area of relatively low pressure extending from the center of a region of low pressure. Air in a high pressure area compresses and warms as it descends. This warming inhibits the formation of clouds, meaning the sky is normally sunny in high-pressure areas.
What do isobars connect?
Isobars: lines of constant pressure. A line drawn on a weather map connecting points of equal pressure is called an "isobar". Isobars are generated from mean sea-level pressure reports and are given in millibars.
