An ultrasonic fogger is a device that uses ultrasonic sound waves to break water into millions of individual water droplets that are then sprayed into the air as a thick fog. Ultrasonic foggers are most often used for Halloween decorations as a dry ice replacement. The fog that an ultrasonic fogger produces is not created …
Weather modification refers to willful manipulation of the climate or local weather. Research done in this field goes back to as far as the early 1940s when the US military experimented with cloud seeding to stimulate rain. Today, private corporations have joined the weather modification research effort to protect people, cities and assets from the …
The Coriolis effect is the tendency for a moving body that is on or above the Earth’s surface to drift sideways from its intended course due to the Earth’s rotation. The direction of drift is to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is because the Earth’s …
When the Earth begins to get too hot, the water increases in temperature. As the water continues to get hotter, it begins to undergo a phase change in which water turns to gas. The water droplets turn into water vapor because the temperature has caused the individual water molecules to speed up considerably. This process …
Lightning can be described as a massive discharge of electrical energy that can reach the speed of 130,000 mph and can exceed temperatures of 30,000 degrees Celsius. Although we know a lot about this phenomenon, it is still unclear how and why lightning forms. We will mention some of the theories on how lightning is …
Blizzards are severe storms which are marked by extremely low temperatures, high-speed winds and substantial snowfall. They are formed when a region of high atmospheric pressure, termed as a ridge, interacts with a region of low atmospheric pressure. As a result of this, a phenomenon known as advection takes place, in which there is a …
There are three stages to a thunderstorm’s life cycle: the cumulus stage, the mature stage, and the dissipation stage. When a thunderstorm begins to form, it does so at the cumulus stage. From there, the storm advances in severity until it reaches its peak at the mature stage and then begins to gradually die out …
A hot water circulator (circulator pump) is a device that circulates hot water through a house’s pipes so that hot water is always instantly available. In traditional one-way plumbing systems, water is run through a hot water heater and directed through the pipes towards the taps whenever a tap is turned on. When a tap …
An air scrubber is a device that removes particles, gases, or chemicals from the air in a specific area. Air scrubbers are very important in some industries as workers are frequently exposed to harmful substances. Most air scrubbers are made for a specific type of air purification but some are made to handle particles, gases, …
An air exchanger is a device that transfers stale air from inside a home to outside, and fresh air from outside to the inside. Air exchangers are often large and built directly into a home’s foundation in order to provide maximum fresh air levels at all times. This is important because indoor air is often …
