Others Like “Flash Floods”

Science Fair Project Idea
Floods can be very destructive, capable of leveling whole towns and decimating crops and fields. Typically in regions prone to flooding there are cycles of flooding that occur, usually in areas where a wet season comes after a period of drought. You can use precipitation data to test if incidents of flooding have been preceded by periods of drought. Look for long periods of dryness in the precipitation data to indicate a drought. You can also conduct an experiment on dry or moist soil to see… Read more

Temperature also changes with latitude. As you move away from the equator, the temperature tends to decrease. Test this by comparing weather data from weather stations at different latitudes.

Ocean currents have a huge impact on our weather. If not for the ocean currents, the global climate would be similar to an ice age. Do you live near the coast? Find out which currents are near your coastline. How do they affect your climate? Where do they come from? Do they bring colder or warmer water to your area? Are they seasonal? What do you think your area would be like without them? Every three to seven years there is a weather phenomenon called El Niño, which is caused by… Read more

As you move up or down in altitude or elevation, the temperature and pressure will change. This is particularly striking if you live near a mountain range. During the summer, at low altitudes you may have temperatures in the 80's or 90's and still be able to see snow on mountain peaks at high altitude. You can test the effect of altitude by comparing temperature data from weather stations at high and low altitudes. You can test the effect of elevation by making your own weather balloon and… Read more

How does temperature change as barometric pressure changes? You can make a device to test this using a barometer and a thermometer on your stovetop. You can collect your own weather data from a barometer and thermometer over a period of a week or month. You can also use data from a weather station to plot the relationship between barometric pressure and temperature. Does the pressure change as humidity changes? Measure the pressure in a humid and non-humid environment (like your bathroom… Read more

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.

If you live in a humid environment, then you know that summer is not only hot, it is downright muggy. You can test the effect of humidity on temperature by measuring the temperature and humidity in your bathroom while running the shower. You can also use historical weather data to compare average seasonal temperatures in humid (e.g., Florida) and dry (e.g., Arizona) regions. How does humidity relate to temperature? Pressure? Why do humid environments tend to be coastal or tropical? How does… Read more

Tornadoes are a very destructive weather phenomenon that is very hard to predict. Certain weather conditions can indicate if a tornado is likely to occur, but the path that the tornado will take is completely unpredictable. Storm chasers are people who chase tornadoes and try to capture them on film or video. They often have a sense of predicting where and when a tornado will strike, but the best images are also due to a bit of luck and survival instinct. Even though tornadoes are… Read more

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… Read more

Unless you live in the Southern states, you only hear about the most destructive hurricanes. In fact hurricanes occur every year, even multiple times a year. Each hurricane is a tropical storm related to cyclones and tornadoes, some big and some small. Each hurricane is measured based upon several variables like: wind speed, diameter, direction of movement and speed of movement. Does the size of the hurricane correlate with the wind speed? What information can the eye of the hurricane… Read more
