Science Thoughts 11/29 What causes the air masses to rise and fall in the atmosphere? Density of the air changes with temperature.

Science Thoughts 11/30 Why is warm air less dense than cold air? Molecules have more energy so moving more and need more space. Same mass, bigger volume means less density.

Severe Weather Notes Type of storm What is it? Blizzard/ Winter Storm Flood Hurricane Thunderstorm Tornado How does it form? Precipitation freezes Severe storm in the winter that can last for and falls as snow, sleet or rain. 3 keys – several days cold air, moisture, lift A rapid rise of water along a stream or low Heavy rain, dam/levee lying area break, ice melt Organized rotating Heat and energy weather system, contact warm waters, develops in tropics wind spirals What are the dangers? Flooding, avalanche, ice jams Death, cars swept off road, water damage Flooding, high winds, storm surge Lighting, thunder, hail 3 keys: Moisture, unstable air, lift. Flooding, fires Violently rotating column of air extending from cloud to the ground Change in wind direction creates horizontal spinning effect High winds, trees uprooted Draw a diagram of the storm
