Questions & AnswersHello I'm weather announcer Melissa Schenk and on behalf of Expert Village today we're going to be talking about the weather. In this segment let's talk about fronts and pressure systems of course when I'm talking about a front I'm referring to a warm front or a cold front to a high pressure system or a low pressure system. There's a course to many different types of front but I only cover the basic so we're talking about a low pressure system if your looking at a map an L represents a low pressure system a low is a regional pressure or a low center that usually a accumulating precipitation, moderate winds or extensive cloudiness. So around a low is usually where you will see rain this is usually now a high pressure system of course is the opposite of that. It's marked with an H on the maps and it usually does indicate fair weather, associated with a high and a low pressure system this where the fronts comes into place a warm front is a front that really moves in away that it replaces the cold or the cooler air. A cold front is on the leading edge of a relatively colder air mass and it separates these 2 air masses so if you have a high pressure system or a low pressure system and it's usually your going to have a warm and a cold front associated with this. Now there are other types of fronts too a stationary front for instance a stationary front very interesting basically it is just that it lies stationary it doesn't go it doesn't move very quickly. So sometimes with even stationary fronts if your getting a lot of rainfall for instance this is where flooding can come into play cause the rain is not moving the winds are not carrying the rainfall at a faster pace so therefore if you have a stationary front and the rain is falling you got precipitation, your going to have flooding in the area because it's not moving and the rain is coming down in one area. So that's just very very basics about warm front, cold front, stationary front and a high and low pressure system.
