A front is a boundary between two different types of air masses, these are normally warm moist air masses from the tropics and cooler drier air masses from polar regions. Fronts move with the wind so over the UK they normally move from west to east. The notes below provide information about the most common types of fronts. The descriptions given ap...
A warm front indicates that warm air is advancing and rising up over the colder air. This is because the warm air is ‘lighter’ or less dense, than the cold air. Therefore warm fronts occur where warmer air is replacing cooler air at the surface. As the warm front approaches there is a gradual deterioration in the weather. Clouds gradually lower fro...
A cold front indicates that cold air is advancing and pushing underneath warmer air at the surface. This occurs because the cold air is ‘heavier’ or denser than the warm air. Therefore cold fronts occur where cooler air is replacing warmer air at the surface. The passage of weather associated with a cold front is much shorter lived than that with a...
In a mature depression the warm front normally precedes the cold front. Cold fronts generally travel much quicker than warm fronts, and eventually it will catch up with the warm front. Where the two fronts meet, warm air is lifted from the surface and an occlusion is formed. An occlusion can be thought of as having similar characteristics to both w...

Weather is the state of the atmosphere at a given time and place, influenced by various factors such as air pressure, temperature, humidity, and wind. This chapter introduces the basic concepts and mechanisms of weather processes and systems, such as the water cycle, air masses, fronts, and cyclones. Learn how these phenomena affect the climate and life on Earth with Geosciences LibreTexts.

4 days ago · 8.5: Weather and Wave Cyclones. The weather associated with the passage of a wave cyclone is a product of the convergence and frontal uplift found in the system. The wave cyclone can be divided into three sectors: (1) the cool sector ahead of the warm front, (2) the warm sector between the cold and warm fronts, and (3) the cold sector located ...
May 9, 2011 · The last post in the weather education series (now three weeks ago!) dealt with upper-air maps, including pressure surfaces and the basics of how to read upper-air maps. The last segment of reading weather maps will be on soundings, but I will break it up into two posts.
