Meteorology for Kids Dylan hunt, Ryan Thompson
Awesome Atmosphere :) ● There are four parts to our atmosphere. The Troposphere, Mesosphere, Thermosphere, Stratosphere. ● Troposphere- Is where all of the weather happens. It is the closest to the surface. ● Stratosphere-Sits on top of the troposphere It contains the ozone layer. ● Mesosphere-Sits above the stratosphere ● Thermosphere-This is where meteors burn up! This is also where the aurora borealis appears.
Crazy Convection Fun :) Convection is like water in a river, the air around us moves. The sun shines on the surface and the air that is heated floats up, when it cools down it sinks back to the surface. The sun shines more at the equator than at the tips of earth(north and south poles), So the heated air moves towards the cooler air at the poles and so the process begins again.
Wacky Wind Current :) When the sun warms the Earth's surface, the sun warms the atmosphere too. parts of the Earth get direct rays from the sun all year and are always warm. Other parts receive indirect rays, so the climate is colder. The Warm air that weighs less than cold air rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow.
Happy High pressure :) High pressure fronts are normally caused by high air that cools and becomes denser which moves toward the ground. Pressure increases here because more air fills the space that is left from the low pressure front. The front also evaporates most of the atmosphere's water vapor so high pressure systems are usually associated with clear skies and calm weather.
Lazy Low Pressure :) A low pressure front is an area where the atmospheric pressure is lower than it usually is, in a normal area.Low pressure fronts are usually have high winds, warm air, and a change in the pressure.low pressure front normally produce clouds, precipitation, and other bad weather like tropical storms.
Fun Front :) Warm Front- Forms when a moist, warm air mass slides up and over a cold air mass. Cold Front-Forms when a cold air mass pushes under a warm air mass, forcing the warm air to rise. Occluded Front-Forms when a warm air mass gets caught between two cold air masses. The warm air mass rises as the cool air masses push and meet in the middle. Stationary-Front Forms when warm and cold air meet and neither air mass has the force to move the other. They remain stationary, or â€œstanding still.â€?
Hurricane Heartbreak ): Hurricanes form with a high pressure system surrounding a low pressure over the ocean. The warm air flows into the cool air in a spiral kind of way. Then more warm air replaces the gap.
Tornado Terror ): Tornadoes are formed when warm air from the gulf meet with frozen air from canada. When the two air masses meet they create uneasy changes in the atmosphere. Change in wind direction and an increase in wind speed. This creates a horizontal spinning effect in the lower atmosphere.
Super Sun :) Our sun is one special star. It gives the energy that drives convection currents in the atmosphere and the oceans. It makes winds and ocean currents.
Wicked Weather :O
Impeccable Isotherms Isotherms are lines of constant or equal temperature. They are often used on weather maps by meteorologists to give a large scale view of temperatures across the U.S. Isobars are lines of constant or equal pressure on a weather map. They can be used to find areas of low or high pressure over a big area.
Precipitation There are 4 types of precipitation; rain, snow, sleet, and hail. Rain is when the condensed water falls to earth in a liquid form. Snow is when the condensed water falls to earth as small frozen crystals. Sleet occurs when the water that falls back to earth is half frozen and half liquid. Hail is when the water that falls back to earth is completely ice.
Clouds Clouds are big fluffy groups of water droplets that float around us every day! They are formed when the water in the air condenses together and makes one giant cloud! Clouds form like this: 1. Water gets into the air through evaporation or perspiration 2. Warm groups of air rise slowly into bigger groups 3. The rising air starts to make larger groups and bigger streams called "thermals" 4. The water in the thermals condenses and makes clouds Or: A large group of warm himid air moves over a big group of cool dry air, which makes the water condense along the boundary of the cool and warm air masses. When the water condenses, it makes clouds!
Dew Point The dew point is the temperature when water can start to form into drops. The little drops combine to make bigger drops, and eventually clouds! Dew is the water that you find on the grass in the morning. The temperature dropped below the dew point, so the water in the air dropped and condensed on the grass.
How scientists get Images Scientists get images from space! When the scientists launch a rocket, it carries a satellite. They use the satellite to take pictures of the things that they need. We also use satellites for things like weather, cell phones, and even TV!
meteorological Instruments used by scientists Some of the tools that scientists use to get data are barometers(measures air pressure), thermometers(air temperature), rain gauge(measures the amount of rain), anemometer(measures wind speed), and many more! All of these instruments have important roles in predicting and showing our weather!
