# What do closely spaced isobars on a map indicate about the wind?

## What do closely spaced isobars on a map indicate about the wind?

Closely spaced isobars indicate a steep pressure gra- dient and high winds. Widely spaced isobars indicate a weak pressure gradient and light winds.

## What do isobars on a weather map represent?

Isobars are lines on a weather map that join places of equal pressure. Meteorologists collect information from weather stations, buoys and ships and then draw smooth curves to join the dots.

What would lines very close together indicate on an isobar map?

The spacing between isobars represents a pressure differential between those two isobars. When two isobars are closer together then the pressure changes at a greater rate over distance. It is pressure differences that set the air in motion.

### How does the spacing of isobars on a weather map relate to wind speed quizlet?

How does the spacing of isobars on a weather map generally relate to the speed of wind? Closely spaced isobars indicate a strong pressure gradient and high wind speeds; widely spaced isobars indicate a weak pressure gradient and low wind speeds. The meteorologist comments that the pressure tendency is rising.

### Why are the Isobar lines close together near the area of low pressure?

Isobars are lines/areas of equal pressure represented on a weather map. 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 a closed Isobar?

An isobar is defined as being closed if its numerical value exists on all 576 radial legs.

## What does a an isobar that is a closed circle represent?

What does an isobar that is closed circle represent. They represent high and low pressure area.

How does the spacing of isobars on a weather map generally relate to the speed of wind quizlet?

### What does an isobar represent on a weather map quizlet?

On a weather map, what does an isobar represent? High pressure guarantees nice weather.

### What does it mean when isobars are close together quizlet?

Isobars that are close together indicate a large pressure. A large pressure causes strong winds. Isobars that are spread apart indicate a smaller pressure.

What is the purpose of isobars?

Definition of an Isobar An isobar is a line on a map that shows a meteorologist what the pressure is at the surface of the earth. They are lines that connect equal points of pressure. Isobars can be used to map atmospheric or air pressure in a way that makes it easier to understand.
