Write an article about the meteorological knowledge you know.

First of all, meteorological terms

(1) Weather maps and satellite cloud pictures

The charts used to analyze the physical conditions and characteristics of the atmosphere are collectively called weather charts.

There are mainly ground weather maps.

And high-altitude weather maps. Satellite cloud pictures are pictures of clouds sent back by meteorological satellites.

It can display a wide range of cloud conditions and is one of the reference bases for weather forecast.

(2) the ground isobar and

3000 meters

Above the sky,

308

line

Because precipitation clouds are mainly formed in

3000 meters

About the sky, this analysis.

700 hectopascals

Homogeneous element

Weather conditions are particularly important. It is often mentioned in the weather broadcast.

3000 meters

Above the sky,

308

line

exist

......

One line ",

involve

700 hectopascals

In order to know the weather condition of isobaric surface,

Therefore, it is called "

3000

Above the sky ",

308

This line is atmospheric pressure.

700 pa

, the potential height is

3080 meters

(In Miri, this is the case.

308

Contour lines connected by all parts of the instrument).

(3) High pressure and high pressure ridge

When analyzing the weather map,

Some isobars are closed curves,

If the air pressure in its center is higher than that around it.

Waist circumference,

This area is called the high-voltage control area,

Where the air pressure is the highest,

It should be called ...

"high

Press the center. "From the high pressure center outward, the air pressure gradually decreases. Due to pressure in all directions

The descending speed is different,

So the isobar is not a set of concentric circles centered on the high pressure center.

atmospheric pressure

The slowly descending part,

Isobaric lines protrude outward from the high pressure center,

Protruding part,

It should be called ...

"high

Press the spine. "Where high pressure (or ridge of high pressure) controls, the air is affected by the rotation of the earth.

When in use, it will be dispersed clockwise continuously, and air will sink to supplement it when it passes.

The air that flows away. It is usually sunny to cloudy near the high pressure center.

(4) Low pressure, low pressure tank

When analyzing the weather map,

If the air pressure in the closed isobar is lower than the air pressure around it,

It is called low pressure.

(abbreviation

"low pressure")

The place with the lowest air pressure in the low pressure area is called the "low pressure center"
