What does isobar mean?

What does isobar mean?

Definition of isobar 1 : an imaginary line or a line on a map or chart connecting or marking places of equal barometric pressure. 2 : one of two or more atoms or elements having the same atomic weights or mass numbers but different atomic numbers.

What do the numbers on isobars indicate?

Isobars are lines of constant pressure which are measured in units called millibars. The numbers indicate the amount of air pressure, in millibars, that each line represents.

What does an isobar represent on a weather map?

Isobars: lines of constant pressure. A line drawn on a weather map connecting points of equal pressure is called an isobar. The isobars are generated from mean sea level pressure reports and the pressure values are given in millibars. The diagram below depicts a pair of isobars.

What do isobars close together indicate?

When isobars become very tightly grouped together it indicates a “tight pressure gradient” (steep slope). The tightly packed isobars are due to the difference in air pressure between between High and Low pressure systems.

What is isobars very short answer?

Isobars are defined as. The atoms that have same number of nucleons. Isobars of different chemical elements have different atomic number but have the same mass number.

What is an isobar quizlet?

Isobar. a line connecting points on a line with the same air pressure. Air Mass. a huge body of air that has similar temperature, humidity and air pressure throughout.

How do isobars help meteorologists?

Meteorologists use isobars on weather maps to depict atmospheric pressure changes over an area and to make predictions concerning wind flow. The greater the contrast in pressure difference between two areas, the faster the wind will blow, so closer isobars on a weather map predict higher velocity winds.

What is isobar diagram?

An isobar is a curve drawn through points of equal pressure. For example, it could be a line joining states of equal pressure in a graph representing thermodynamic processes.

How do isobars predict weather?

What do you mean by isotope and isobar?

Isotopes are atoms with the same number of protons but differing numbers of neutrons. Isobars are atoms of different chemical elements having equal values for atomic mass. Isotopes have the same atomic number. Isobars have different atomic numbers. Isotopes have a different atomic mass.

What is the difference between isobars and isotherms?

As nouns the difference between isotherm and isobar is that isotherm is a line of equal or constant temperature on a graph or chart, such as a weather map while isobar is (meteorology) a line drawn on a map or chart connecting places of equal or constant pressure.

What do the numbers on the isobars mean?

Isobars are lines on a weather map joining together places of equal atmospheric pressure. On the map the isobar marked 1004 represents an area of high pressure, while the isobar marked 976 represents an area of low pressure. The numbers measure the atmospheric pressure in millibars.

What do isobars represent?

Isobars are lines on a weather map joining together places of equal atmospheric pressure. On the map the isobar marked 1004 represents an area of high pressure , while the isobar marked 976 represents an area of low pressure .

What do isobars show on a weather map?

Isobars are lines that connect points of equal atmospheric pressure on weather maps. Isobars are similar to height lines on a geographical map, and they are drawn so that they can never cross each other. Meteorologists use isobars on weather maps to depict atmospheric pressure changes over an area and to make predictions concerning wind flow.
