This bingo card has a free space and 34 words: an air mass is a large body of air with the same temp and humidity, air masses can be cool, warm, humid, or dry, areas near the equator are warmer, areas near the poles get sunlight at a low angle, air masses can move from the areas they form in, when air masses collide we get dramatic changes in weather, prevailing winds blow in one direction over a certain region, air masses take on the characteristics of the regions they form in, winds are caused by the uneven heating of the earth, warm air rises near the equator, as it move towards the pole air cools down and sinks, warm air rises and cold air sinks, weather front is the boundary between two air masses, there are 4 main types of weather fronts, a cold front happens when cold air mass moves into an area, because the boundary at a cold front is so steep big clouds can form, when a cold front passes through an area the temperature drops, a warm front is when a warm air mass overtakes a cold air mass, warm air rises over cold air but it happens at a gentle angle, warm fronts usually provide lighter rain, in a stationary front the winds are light, an occluded front forms when an air mass becomes separated, it sweeps into the area and pushes the warm air mass up, the warm air mass gets stuck above the two cold air masses, the word occluded means blocked off, occluded fronts can bring heavy rain, winds can travel in different directions in different heights, scientists predict the weather using probability, weather is difficult to predict, ocean currents affect weather too, high pressure systems bring clear sunny weather, low pressure systems bring cloudy rainy weather, air spins clockwise in a high pressure system and air spins counterclockwise in a low pressure system.
