2 Formation of Clouds Flow Chart: Create a flow chart describing the formation of clouds, correctly ordering the statements belowAir eventually becomes saturatedMillions of droplets of liquid water collect to form a cloudWarm air rises and cools.Water vapor condenses on smoke, dust, salt and other small particles suspended in the airWater vapor is added to the air (evaporation)
3 How Does a Cloud Form? 1. Warm air rises and cools 2. Water vapor is added to the air (evaporation)3. Air eventually becomes saturated4. Water vapor condenses on smoke, dust, salt and other small particles suspended in the air5. Millions of droplets of liquid water collect to form a cloud
27 TornadoesTornados: Violent whirling wind that stretch from the cloud to the groundMost occur in North America
28 Formation of Tornadoes Warm air masses from Gulf of Mexico move north and meet cold, dense air and form thunderstormsStrong upward movement of air cause a vertical cylinder of rotating air, also called a mesocyclone to form.
37 Cyclone, Hurricane, Typhoon… oh my Same type of storm, just form and occur in different oceans!Hurricane = Atlantic ocean, Eastern pacific including Hawaiian islandsTyphoon = Western pacificCyclone = Southern pacific and Indian oceanCheck for understanding: What do we call our storm?
38 What Is a Hurricane?A Hurricane is a large, swirling, low pressure system that forms over tropical oceans.Has wind speeds of at least 74 mphIn other countries they are also known as typhoons and cyclonesWhat states they hit:
39 HURRICANESThe wall that is created from the air rising is called an eye wall.The eye is the center of the hurricane.In the eye there are no winds or precipitation.Only calm spot in the storm.
41 When do hurricane’s happen? Critical Thinking: What season do you think is Hurricane season in the US?(hint: think about warm waters or make a life-connection and think about when you have heard about them on the news!)The Atlantic Ocean, Caribbean Sea and Gulf of Mexico hurricane season runs from June 1 through Nov. 30.Most hurricanes occur from around the middle of August through the middle of October
42 Can anything stop these powerful storms? Critical Thinking: Hurricanes depend on the tropical warm water and the evaporation in order to keep shape… so what do you think could stop them?As hurricanes travel over colder water or over land they lose their evaporation which causes them to weaken.
43 Just shy of hurricane:Tropical Depression An organized system of clouds and thunderstorms with a defined surface circulation and maximum sustained winds* of 38 mph or lessTropical Storm An organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds of mph
44 Hurricane Categories: Category One Hurricane (Sustained winds mph, kt, or km/hr)-- Very dangerous winds will produce some damageCategory Two Hurricane (Sustained winds mph, kt, or km/hr)--Extremely dangerous winds will cause extensive damageCategory Three Hurricane (Sustained winds mph, kt, or km/hr)-- Devastating damage will occurCategory Four Hurricane (Sustained winds mph, kt, or km/hr)--Catastrophic damage will occurCategory Five Hurricane (Sustained winds greater than 155 mph, greater than 135 kt, or greater than 249 km/hr).-- Catastrophic damage will occur
45 Damage Caused by Hurricanes Hurricane winds can knock down trees and telephone polesHowever, the most damage during a hurricane comes from flooding due to heavy rain and storm surgesA storm surge is a wall of water that builds up over the ocean and can be up to 20 feet before it crashes onto the shore

50 Fish Are Falling On My Head! Have you ever heard of fish falling from the sky? Well, check this out!
51 It’s raining fish….Residents of a small outback Australian town have been left speechless after fish began falling from the sky. Hundreds of spangled perch bombarded the 650 residents of Lajamanu, shocking local Christine Balmer, who was walking home when the strange 'weather' started. She said: 'These fish fell in their hundreds and hundreds all over the place. The locals were running around everywhere picking them up.
52 ‘The fish were all alive when they hit the ground so they would have been alive when they were up there flying around the sky.' When I told my family, who live in another part of Australia, about the fish falling from the sky, they thought I'd lost the plot.' But no, I haven't lost my marbles. All I can say is that I'm thankful that it didn't rain crocodiles!
