At the equator, intense sunlight warms the air and causes evaporation of water from the ocean. As the air heats up, it expands and rises.

Why does the warm moist air rise at the frontal boundary?
Because colder air is forcing it upward.
What happenes as lower layers of air are warmed?
When lower levels of air are warmed they rise into upper atmospheres. As warm air rises, it causes wind. If the warm air is moist, it will cause thunderstorms and possibly even tornadoes if it rises quickly enough.
What happen when warm moist air rises?
When warm moist air rises it cools and condenses.
What of following causes tornadoes?
wind shear- earth science
Convection currents form when warm air rises and cold air sinks What causes the warm air to rise and the cold air to sink?
a difference in density
What is the primary energy source that causes warm moist air to rise over tropical oceans?
The heat of the sun.

What is orthographic precipitation?
Created when warm, moist air is forces to rise over a barrier. (mountain).
What air masses would have warm moist air?
Maritime tropical air masses are warm and moist.

When warm moist air rises it cools and condenses.
What of following causes tornadoes?
wind shear- earth science
what type of flight causes birds to rise in warm air?
It is caused when a bird runs into warm air and it causes it to fly. About any bird will fly when they run into warm air, except the ones that can't fly.
Why are thunderstorms often assocciated with the arrival of a moving cold front?
The warm air mass carries warm moist air. The cold front brings cold, dense air. Because this cold air is denser, as it ploughs through the warm moist air it forces it upwards. This warm moist air being pushed up at speed is what causes cumulonimbus clouds to form along the cold front, and hence thunderstorms.
Convection currents form when warm air rises and cold air sinks What causes the warm air to rise and the cold air to sink?
a difference in density
Convection currents form when warm air rises and cold air sinks. What causes the warm air to rise and the cold air to sink?
a deference in density
What causes air mass?
No single air mass "causes" tornadoes. This is Tornadoes form within thunderstorms. Thunderstorms form best when there is plentiful warm, moist air. So, a arm, moist air mass is usually present. Significant tornado activity, however, usually results from the thunderstorms that form near the boundaries between air masses. Usually where a warm, moist air mass meets a cooler or drier air mass.
