The precipitation associated with a warm front typically arrives when?
considerably ahead of the actual frontal boundary
What are stationary fronts and what type of weather is associated with them?
When a warm or cold front stops moving, it becomes a stationary front. Once this boundary resumes its forward motion, it once again becomes a warm front or cold front. Stationary fronts may bring several days of clouds and precipitation as air is constantly forced to rise, and multiple low pressure systems can move over the frontal boundary bringing with it rain, snow, and potentially wind.
What happen when warm moist air rises?
When warm moist air rises it cools and condenses.
What are some of the events that must occur to create a hurricane?
warm waters and moist air. the water starts to rise and the condensation forms clouds and raindrops.
3 types of rainfall and where each type is likely to occur?
There are three main types of rainfall, convectional rainfall, relief rainfall and frontal rainfall. Relief rainfall is when the warm moist air from the sea (Atlantic Ocean) is forced to rise over mountains and as the moist air gets higher it gets colder so it gradually condenses and becomes water droplets and it rains/ prcipitates. Relief rainfall is common along the west side of Britain where there are more high lands. Convestional rainfall is when the sun comes out and heats up the land, this causes the air around it to become warm too. The warm air currents rise and as it rises it gets colder so it gradually condenses and the water vapou become water droplets and it rains/precipitates. Convectional rainfall is mostly common around towards the south of Britain in the summer. Frontal rainfall is when cold air and warm air meet, the warm, light air wants to get past the heavy cold air so it casually rises above it. Its rising makes it get colder which makes the warm air cold air, it condenses and guess what? It rains/ precipitates! Frontal rainfall is mostly common all over Britain especially in the winter.

How do tornadoes occur at frontal boundaries?
At a frontal boundary warm, moist air can be lifted upwards, where the water vapor in it cools, and condenses producing clouds, rain, and sometimes thunderstorms. When these thunderstorms interact with another condition called wind shear, they can start rotating. In some of these storms that rotation can develop into tornadoes.
What is orthographic precipitation?
Created when warm, moist air is forces to rise over a barrier. (mountain).
What type of air does a tornado need in order to develop?
Generally tornadoes form near a boundary between warm, moist air and cool, dry air. The warm, moist air mass is more important as it provide the energy that fuels the storm.
What is the primary energy source that causes warm moist air to rise over tropical oceans?
The heat of the sun.
What are all the 4 fronts and what do they do?
Warm front--rise in temperature; gentle rain; longer duration Cold front--drop in temperature; violent precipitation including storms; shorter duration Stationary front--many days of precipitation along the frontal boundary Occluded front--precipitation
What are stationary fronts and what type of weather is associated with them?
When a warm or cold front stops moving, it becomes a stationary front. Once this boundary resumes its forward motion, it once again becomes a warm front or cold front. Stationary fronts may bring several days of clouds and precipitation as air is constantly forced to rise, and multiple low pressure systems can move over the frontal boundary bringing with it rain, snow, and potentially wind.
What is frontal rainfall?
Frontal rain is rain that comes from a weather front. For example, a cold front lifts warm, moist air. This parcel of air is raised to the LCL, and higher. Saturation occurs first, and then precipitation forms. Frontal rainfall is when cool air and hot air meets together. the warm air rises above the cool air.the warm air eventually cools down and water vapour condenses then clouds forms and precipitation occurs.
What happen when warm moist air rises?
When warm moist air rises it cools and condenses.
What is frontal wedging?
Frontal wedging is when warm air and cold air collide at the surface, or front.
What are some of the events that must occur to create a hurricane?
warm waters and moist air. the water starts to rise and the condensation forms clouds and raindrops.
What air masses would have warm moist air?
Maritime tropical air masses are warm and moist.
