You have obviously noticed that at each and every day, the weather changes. One day may be very rainy and the other day very sunny, the favourite time for a walk to the beach. But have you ever stopped and asked yourself, what causes all these changes? A lot of factors affect the weather system thus causing the different changes of every day. This is the reason why weather forecasters may predict that a day will be sunny but the day ends up to be rainy. It is due to the different factors that influence the weather system. Among these factors is the pressure system. In a weather report, it is marked with L or H in a map of the weather. Therefore, what are the 5 things you did not know about pressure systems?
The first one is, what are pressure Systems?
A pressure system is an area of the atmosphere of the earth which has either a low or high pressure based on the air surrounding that area. Basically, Pressure is all about how far air molecules are from one another. High pressure is when air molecules are highly packed together while low pressure is when the air molecules are spread out to each other. Of course, it’s not just related to weather, you’ll find pressure systems safety regulations in your home, for your boiler, compressor or heater. There are many systems that rely on pressure, so they too will have their own pressure systems, so to speak.
Secondly, what causes pressure systems?
Pressure systems are caused by different factors such as the different motions of air currents in a specific or given area, the terrain of the area and the presence of a nearby water body. In the case of terrain, it’s all about the presence of mountains or is the area flat while for water bodies, it’s about the presence of a sea, lake or even oceans.
Thirdly, how do pressure systems affect weather?
If there are high-pressure tides, the weather of the day will have warm temperatures and a sky that is very clear. While in a low-pressure air, the weather turns out to be cloudy and very rainy. This variation of the weather is caused by changes in pressure systems.
Next, what are the types of weather in high pressure?
High-pressure zones are also referred to as anticyclones and are represented by letter H on the map meaning the zone has high pressure than the around the air. The types of weather caused by high pressure are:
– High pressure from the north will cause cold weather while that from the south will case cool weather.
-High pressure will cause more wind to blow.
– It will cause a cloudless sky.
– It will also cause drier weather because the sinking air will increase in pressure leading to less precipitation.
Lastly, what are the types of weather in low pressure?
Low-pressure zones are also called cyclones. And since low pressure is lighter and less dense, the air rises causing the following types of weather:
– More clouds to form.
– It will cause more cold and rainy weather due to the high rate of precipitation.
– Less amount of wind to blow.
