Weather School Part One: Pressure

Welcome to my first part of my own little weather school, I will start with something easy like pressure.
-------------------------------------------------
Pressure is measure of how much force a object has against a surface. The earth atmosphere has a standard pressure who is 1012 hPa. When a meteorologist are talking about high pressure or High they are talking about a region with a higher pressure then in the rest of the vicinity.

The fact of that high pressure often are connected with a beautiful weather is because of the vertical wind (downward) who create a region who has less clouds then a region with a standard pressure.

A low pressure is often connected with cloudy and rainy weather, this is also because of the vertical wind (upward) who here is contributing to the genesis of clouds.

If you has some question or want to correct something or if you like this particular entry please comment.

  2. Yeah my first comment, I think that is not less complicated in Swedish. But I give you easy explanation.
    In Swedish:
    Högtryck är ett område med ett luftryck som ökar när du går mot områdets mitt, ett lågtryck är när luftrycket minskar mot områdets mitt
    In English:
    A High pressure area is when the air pressure is increasing towards the centre of the area. For a Low pressure is decreasing towards the centre.
