10 points for help geography master How to understand the law of wind pressure in Bero detailed .

If you are a high school student, you can directly understand that this law describes the relationship between wind and air pressure field. Specifically, in the northern hemisphere, people stand against the wind, with high pressure in the right hand and low pressure in the left hand.

Geostrophic wind is a horizontal movement of air in the free atmosphere at equal velocity and in a straight line when the pressure gradient force and the geostrophic deflection force are balanced. The geostrophic wind direction is perpendicular to the direction of the horizontal pressure gradient force, i.e., parallel to the isobar. Therefore, if it is standing against the lee, the high pressure in the northern hemisphere is to its right, and in the southern hemisphere, the high pressure is to its left, which is called the Berlo wind pressure law.

The geostrophic wind speed decreases with the increase of latitude. However, the observed geostrophic wind speed is greater at high latitudes than at low latitudes. This is due to the fact that the value of the pressure gradient at high latitudes is much greater than at low latitudes.

Since the geostrophic wind is the horizontal movement of the air when g and a reach equilibrium, it is a stable linear motion, and the wind direction is parallel to the isobar, which is also parallel to each other. Strictly speaking, the isobars should also be parallel to the latitude circle, because the geostrophic deflection force varies with the latitude, and only when the contour line is parallel to the latitude line can the balance between the pressure gradient force and the geostrophic deflection force be achieved everywhere to obtain a stable linear motion. In the actual atmosphere, such strictly theoretical geostrophic winds are rare.

The actual winds in the free atmosphere at the middle and high latitudes are very similar to those of the geostrophic winds, and the horizontal movement is basically geostrophic winds. At low latitudes, the geostrophic deflection force is very small, and the concept of geostrophic wind is no longer applicable. For a place with the same latitude, the wind speed of each layer can be determined by comparing the density of the contour lines on the isobaric surface map of each layer.

I won't write about quantitative analysis. This is the conclusion of 90 degrees, if you remember it in high school, it is not from high school, fill in the questions to supplement, and I will push the formula for you.

Also known as the "law of wind pressure". Describe the relationship between wind and pressure fields in large-scale weather systems. Man stands against the wind, with high pressure on the right side in the Northern Hemisphere; The Southern Hemisphere high is on the left.

Dutch meteorologist, physicist. He was born on 10 October 1817 in Clutinge, the Netherlands, and died on 3 February 1890 in Utrecht, the Netherlands. He received a doctorate from the University of Utrecht in 1844, where he taught in 1845 and became a professor in 1867.

In the early days, he studied physics and chemistry, and later studied meteorology. In 1854, he founded the Royal Netherlands Meteorological Institute and served as its director. In 1857, Berro discovered the relationship between wind direction and pressure distribution, known as "Berbero's Law".

In 1866, the first storm siren and dangerous weather signal system were created, and storm warnings were issued. From 1873 to 1879, he served as the first president of the International Meteorological Organization, during which he devoted himself to the unification of international meteorological observation norms. He is the author of "Periodic Changes in Temperature", "Explanation of Storm Lisou Siren", "Proposal on Unifying the International Meteorological Observation System", etc.

Answer]: Berrow's law is also known as the "law of wind pressure". To describe the relationship between wind and pressure fields in large-scale weather systems.

Specifically, in the free atmosphere, wind is basically blown along an isobar. In the northern hemisphere, standing against the wind, the low pressure is on the left, and the high pressure is on the right; In the Southern Hemisphere it is the opposite.

In the friction layer, because the wind direction crosses the isobar diagonally and flows to the low pressure, in the northern hemisphere, the leeward side is in front of the front, and the high pressure is in the right rear. The Southern Hemisphere is the opposite.
