Tools to Measure Weather

Ect weather data. Trackingthe The forecasters have a lot of help! Meteorologists, or scientists who study weather, collect data from all over the world. They use automated systems at sea, on land, in the air, and in space to help track the weather. At sea, weather buoys collect data on coastal weather conditions. These data help keep people in coastal cities safe. On land, weather-monitoring stations track weather conditions in remote locations. They can send advance notice about incoming weather. Scientists also use Doppler radar towers to observe how storm clouds are moving. Weather balloons and weather satellites collect data from high above Earth’s surface. Weather satellites can track the weather over very large areas. They also help relay data from land-based tools to meteorologists around the world. Scientists launch weather balloons that carry tools, called radiosondes, into the atmosphere. A typical radiosonde measures air temperature, air pressure, and humidity. Weather satellites orbit Earth. They collect weather data, such as cloud cover, and track storms, such as hurricanes. These satellites use radio signals to transmit data back to Earth. Packets of air move across Earth’s surface. An air mass is a large body of air with the same temperature and humidity throughout. An air mass reflects the conditions of the place where it forms. Air masses that form over land are dry. Air masses that form over water are moist. Cold air masses form near the poles, and warm air masses form near the tropics. As air masses move across an area, they can collide. The boundary between two air masses is called a front. Weather changes take place at fronts. For example, as a warm front passes over an area, warm air replaces cooler air and the temperature rises. The movement of air masses and fronts explains why you might be chilly one day and warm the next. At a front, stormy conditions are common. Air masses may form over land or water. The masses that form over land near the poles will be cold and dry. The masses that form over water near the poles will be cold and moist. Which types of air masses will form near the tropics? A cold front forms where a cold air mass bumps into a warmer air mass. The denser cold air pushes the warm air up. Water vapor in the air cools, and large clouds form. Thunderstorms and heavy rain often take place. Cooler temperatures follow a cold front. A warm front forms where a warm air mass moves over a cold air mass. A warm front forms a wider area of clouds and rain than a cold front. Steady rain or snow may fall. Warmer temperatures follow a warm front.

MEANING OF CLOTHES Clothes are things worn to cover our body. Examples of clothes are: Pant, singlet, petticoat, shirt, blouse, gown, trousers, knickers, waist – coat etc. Clothes can be made through processes like sewing, knitting and crocheting. Sewing, knitting and crocheting can be done using simple tools like needle, scissors, measurement tape and sewing machine. THE FOLLOWING ARE THE REASONS FOR WEARING CLOTHES: 1. To cover our nakedness. 2. To prevent us from cold. 3. To protect us from harsh weather. Example harmattan season. 4. To look beautiful and attractive. 5. To look decent. 6. For easy identification. 7. To keep us warm.

All About Kites Introduction. A kite is one of the oldest toys. And it's very simple to make. Kites come in many sizes, shapes, and colors. Did you know that kites can be both toys and tools? History of Kites. Kites were named after the kite bird. The kite bird has wide wings and easily floats high in the sky. No one knows who made the first kite. But one famous Chinese story about a kite was written over 2,000 years ago. The story is about a man who used a kite to attack a fort. He couldn't find a way to get inside the fort. So he tied himself to a huge kite. He flew over the wall of the fort and scared the soldiers! The inventor Ben Franklin had the idea that lightning was made of electricity. He wanted to prove his idea. One day when it was stormy, he tied a metal key to a kite string. Then he flew the kite up into the storm clouds. Lightning from the storm hit his kite. The electricity ran down the wet string to the metal key. When he reached for the key, he got a surprise. The electricity jumped from the key and gave him a shock! Do not try this yourself. It's not safe to do. When Ben Franklin tried to do it again, he was hurt badly. Many Uses for Kites. Some people have used kites for fishing. They put a fishhook and bait on the long kite tail. The kite tail dragged in the water. When a fish saw it, it bit the bait and was caught on the hook. Then the kite was pulled in. Weather kites carried scientific gauges into the sky. The gauges measured how fast the wind was blowing and how cool the air was. Years ago, some armies used kites with cameras to spy on enemy troops. Kites were also used as flying targets. The kites trained soldiers to aim better. Soldiers shot at the kites. The moving kites were hard to hit with bullets. Different shapes of kites fly in different ways. Flat, diamond-shaped kites fly easily. Box-shaped kites can hang still in the air for a long time. Stunt kites twist and twirl on many strings. Large parafoil kites act almost like parachutes. Giant dragon kites flutter. Fighting kites can be used to cut other kites' strings. On a breezy day, take your kite to a flat, open area. Be sure that there are no power lines or big trees. Look at the ground around you. Is there anything you could trip over? Hold your kite up by the bridle and run into the wind. Let go of the kite and slowly let out some string. Then let out a little more until your kite is high in the sky. Happy flying!
