Mystic-spirit gave you an excellent answer about high and low pressures but she forgot to talk about the fronts. Here it is:
If you understand the above, you understand that the poles are regions of high pressures because of the cold temperature. Between those and the sub-tropical belt of high pressure, there are fronts created between air masses of different temperature. Those are roughly at latitudes 60 North and 60 South.
The front is tilted because warm air from the south (in the northern hemisphere) is lighter and climbs over the cold polar air. This climbing creates a low pressure because the air rises. Along the front, low pressures will be born and as they are taken by the jet streams strong winds in the upper atmosphere, will move in an easterly direction, deepening even more in the process; pushing a warm front ahead of it and dragging a cold front behind.
Those are typical frontal lows; as opposed to tropical lows that are created by the sole effect of the very high temperature near the ground.

∙ 14y agoWeather is predicted by a Tevlevision Forcaster. They use fronts and air pressure to determine the weather in several different ways. When a cold air mass runs into a warm air mass, a cold front occurs. When a warm air mass runs into a cold air mass, a warm front occurs. High and low air pressure affect the weather in those areas.

∙ 12y agoAn important characteristic of the Earth's atmosphere is its pressure as it often determines wind and weather patterns across the globe. By definition, atmospheric or air pressure is the force per unit of area exerted on the Earth's surface by the weight of the air above the surface. The force exerted by an air mass is created by the molecules that make it up and their size, motion, and number present in the air. These are important factors because they determine the temperature and density of the air and thus its pressure.

∙ 14y agothe relationship is a lowpressure system is the effect that happens after the front which means bad weather will happen.

Do fronts occur in areas of high pressure?
No, not really. Winds tend to blow out of the High pressure areas to low pressure areas. This causes the clouds to follow the winds and that is the reason why you would expect a nice sunny weather when a high pressure area moves over you.
What factors interact to cause weather?
Weather is caused by the interaction of air,water,and sun. This forms air masses which can soon form fronts where air moves from high pressure areas to low pressure areas.
What types of symbols are used on a weather map to indicate cold fronts and warm fronts?
The symbol for a Cold front on a weather map is represented with a blue line with blue triangles facing the direction that the front is traveling. A warm front is represented with a red line with red half-circles facing the direction of travel.
What information is found on a weather map?
Weather maps can provide information including patterns of weather systems. Forecasts give a summary of the most likely weather that is incoming towards a specific area. For example, the weather forecast for CT for tomorrow is mostly sunny with a high temp. of 78 degrees. This information provides me knowledge of the upcoming conditions.
What kind of weather system is found in areas of high pressure Low air pressure?
Depending on the air pressure the weather system can be hot of cold

What is a line on a weather map called?
There are several different lines on a weather map. Lines with triangles leading out from them are referred to as cold fronts, while lines with semi-circles leading out from them are warm fronts. There are also lines on a weather map that are called isobars. They connect areas of equal barometric pressure.
Why are fronts important?
There are cold and warm weather fronts. On a weather map they are defined by sudden changes in the ambient temperature. For example, in front of a cold front, which typically travels west to east, we find the temperature over the area in front will be several degrees warmer than behind that cold front. Conversely, if it's a warm front, the air in front will be several degree colder than behind that warm front. Typically the cold fronts are created by low pressure areas and warm fronts by high pressure areas. As the names imply, low pressure areas have atmospheric pressures lower than the surrounding areas. And high pressure areas have atm pressures that are higher than the surrounding areas.

What type of weather occures when air pressure is high or low?
Air pressure does make quite a difference in weather. In this question, we are talking about high pressure areas and low pressure areas. In High Pressure areas, this doesn't allow for cloud formation, so we end up getting very nice weather. Low Pressure areas are the exact opposite, this allows for cloud formation, so we end up getting rainy weather. High Pressure Areas are represented with a blue H on a weather map. Low Pressure Areas are represented with a red L on a weather map.
What conditions affect the weather?
Conditions that affect the weather are wind, high pressure, and low pressure areas. Areas of concrete and blacktop heat up fast and can affect the weather.

Type of weather is associated with high pressure areas?
warm weather
Areas of low pressure usually have?
Cloudy weather.
True or false high pressure areas on weather maps are in circle formed by isotherms?
It is False that high pressure areas on weather maps are in circles formed by isotherms.
