Notes

winds move heat and cold temperatures as well as moisture from one place to another, transporting conditions from one geographical zone to another. The way winds pass each other, and the direction they move, also affects what weather a region will see on any given day.
air pressure affects the weather pattern to a great extent. Rising air creates low pressure while sinking air creates high pressure. With high pressure, sinking air suppresses weather development
Air in the atmosphere moves around the world in a pattern called global atmospheric circulation
However the environment far above us impacts their movement. High in the atmosphere, narrow bands of strong wind, such as the jet streams, steer weather systems and transfer heat and moisture around the globe. As they travel across the Earth, air masses and global winds do not move in straight lines
an example of how weather maps use high and low pressure and fronts to influence weather is high pressure (H) areas will have clear skies, while low pressure (L) areas can be stormy. Blue "cold front" lines bring rain and wind in the direction the triangular marks point. Red "warm front" lines bring brief rain followed by warming in the direction of the semi-circles.
On a weather map fronts are drawn where there is large changes in temperature, changes in wind direction and speed, and between areas where there are large changes in pressure. On a weather map, fair weather is generally associated with "Highs" while stormy weather is associated with "Lows" and with the portions of fronts that extend from them.
what do weather maps look like?
On a weather map, you will notice some lines that have semi-circles or triangles on either side, or both. These indicate the boundaries for various types of fronts. Analyze a Cold front. With these weather patterns, rainfall can be torrential and wind speeds can be high. Blue lines with triangles on one side represents cold fronts on weather maps
