Weather & Earth systems Ms. Rachel Holt 5 th Grade Science 5/14/2011

What is the Mexican weather report? Chili today and hot tamale. Whatever happened to that cow that was lifted into the air by the tornado. Udder disaster! Q) How do you spot a happy motorcyclist in fair weather? A) He's got bugs on his teeth.

What about the Weather? What you should expect to learn from this lesson: There are different forms of weather especially precipitation. There are major characteristic differences between different forms of precipitation, such as rain, snow ad hail. There are different temperatures, humidity levels and specific forms of precipitation that are specific to a certain location. There is a connection between weather, temperature and water.

What about the Weather? What you need to know: In a certain region there is a connection to weather because of the temperature of that region. Precipitation is rain, snow, sleet, dew, etc, formed by condensation of water vapor in the atmosphere Hail is showery precipitation in the form of irregular pellets or balls of ice more than 1 / 5 in. (5 mm) in diameter, falling from a cumulonimbus cloud Rain is water that is condensed from the aqueous vapor in the atmosphere and falls to earth in drops more than 1 / 50 in. (0.5 mm) in diameter.

What about the Weather? Snow is a precipitation in the form of ice crystals, mainly of intricately branched, hexagonal form and often agglomerated into snowflakes, formed directly from the freezing of the water vapor in the air. Humidity is a moderate degree of wetness especially of the atmosphere. Temperature is a measure of the warmth or coldness of an object or substance with reference to some standard value. The temperature of two systems is the same when the systems are in thermal equilibrium. Climate is the composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years.

Fun Facts The highest recorded temperature for North America was at Death Valley, CA (Greenland Ranch) the temperature was 134 degrees Fahrenheit. The lowest recorded temperature for North America was at Snag, Yukon, Canada with the record temp of degrees Fahrenheit.

It’s electrifying!!! What is lightning? It is static electricity gone giant- scale. Lightning comes from thunderstorms (and snowstorms and volcanoes). There are some 2000 thunderstorms globally at any one time producing some 100 lightning strikes to earth per second. In the USA, there are about million ground strikes per year. Florida has the most strikes - about 12 strikes per square kilometer per year in some places. On average, more people are killed by lightning than any other weather event. There is more than $2 billion damage annually in the USA from lightning.

It’s electrifying!!! Your risk of being killed by lightning is 1:28,500 per exposed individual. The average flash will light a 100 watt bulb for more than 3 months. Lightning’s heat exceeds 50,000 degrees F. or three times hotter than the surface of the sun. Its’ speed is 90,000 miles per second (one hundred million feet per second). The average thickness of a bolt is 1-2 inches

Remember weather is not something to play with Recently we have all seen the terrors of weather in Midwest more specifically in areas like Joplin, Missouri Click this link to watch the News report about what happened. Then watch it from a storm chasers perspective.Joplin, Missouristorm chasers
