Everybody talks about the weather, but nobody does anything about it.
- Charles Dudley Warner
Weather and atmospheric science offer lots of opportunities for interesting explorations. It's a satisfyingly complex area, with lots of online resources so you can make your project as easy or as advanced as you want. And when you're done, you'll have a science fair project everyone can talk about.
The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do…
Before you head for school for the day, you might check the weather to see whether or not you need to wear a jacket or bring an umbrella. It is pretty easy for you to check the TV or internet to see what the weather will be like today, tomorrow, or even next week. The modern-day science of meteorology, or studying and predicting the weather, has many advanced tools at its disposal that make it easy for you to get this information.
How did people predict the weather before the invention of…
The Sun is the ultimate source of the energy that powers weather systems on Earth. Geomagnetic storms are sun-powered storms in the upper atmosphere, arising from energized particles that are periodically ejected by the Sun. Among other effects, geomagnetic storms can wreak havoc with earth-orbiting satellites, and disrupt satellite communications. The global positioning system (GPS) is a network of 24 earth-orbiting satellites that constantly sends radio signals through the earth's…
Many continents contain large mountain ranges that divide the continent into different regions. In the U.S. the Rocky Mountains mark the continental divide. The presence of a large mountain range can have a big effect on seasonal weather patterns. Also, the weather and climate on one side of a mountain range may be very different from weather and climate on the other side of the range. In the case of the Rocky Mountains, the western slope and eastern slope each have very different climates…
Wind can make a cold day colder, or a hot day more pleasant. Use weather data to test the effect of wind on the temperature. How much of a change on the perceived temperature can the wind make? How is wind shear calculated? How can a wind barrier, like a wind breaker, keep you warm even if there is no insulating material? Build an instrument to measure wind speed or direction.
