However there are some common features typically found of these images. Weather maps as they appear on tv in a newspaper or here are called surface charts or more correctly mean sea level msl charts.
Lecture 8 Surface Weather Map Analysis
Fronts are usually detectable at the surface in a number of ways.
They show what is happening at a set time where most of us need it at the earth s surface. Warm fronts usually move from southwest to northeast. In the section about the origin of wind we have already seen the source of the highs and lows. Weather maps come in myriads of styles with each providing different levels of information.
On a weather map a warm front is usually drawn using a solid red line with half circles pointing in the direction of the cold air that will be replaced. They do not show what is happening at higher levels where the wind flow may be doing something entirely different. How to read surface weather maps. We draw lines called fronts.
It s called a surface weather analysis map and it shows the positions of high and low pressure systems and the boundaries between warm and cold air called fronts. But how are the boundaries between air masses depicted. To read air pressure on a surface analysis weather map check for isobars iso equal bar pressure plain curved lines that indicate areas of equal air pressure. Winds often converge or come together at.
Cold fronts come in association with a low pressure area. Isobars play a major role in determining the speed and direction of wind. Types of weather fronts a weather front is a boundary separating two air masses of different density. On weather maps the surface position of the cold front is marked with the symbol of a blue line of triangle shaped pips pointing in the direction of travel and it is placed at the leading edge of the cooler air mass.
A warm front can initially bring some rain followed by clear skies and warm temperatures.
