A heat wave is roughly defined as a period of abnormally hot weather that generally lasts more than two days. While this definition is rather broad, it has to be because communities in different parts of the country or the world can tolerate heat differently. ...
So all three of these locations did experience a heatwave, by definition. Alexandra was expected to not quite reach temperatures warm enough to count as a heat wave, compared to their average daily maximum temperatures for October and November. However, on the 31st of October and 1st of Novemb...
Heat waves form when “high pressure aloft, from 10,000 to 25,000 feet (3,000 to 7,600 meters), strengthens and remains over a region for several days up to several weeks,” explains the National Weather Service. “This is common in summer (in both Northern and Southern Hemispheres) as...

A heat wave, or heatwave, is a period of two or more consecutive days with apparent temperatures exceeding 105 °F to 110 °F (40 °C to 43 °C) on the National Weather Service's Heat Index. The temperature standards may vary significantly for different cities, states, nations, and regi...
In this case, a ridge of high pressure, which is the heat dome, has become lodged in the Pacific Northwest. It is acting as a block in the atmosphere, not allowing the weather to move. The specific type of block is called an Omega block, because it looks like the greek letter Omega...
sound wave What is a sound wave? A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid orsolidmatter) as it propagates away from the source of the sound....
To fly, drones must have a power source, such as a battery or fuel. They also commonly have rotors, propellers or wings and a frame. The frame of a drone is typically made of a lightweight, composite material to reduce weight and increase maneuverability. ...
A shock wave is a wave that moves faster than the local speed of sound. This results in a sudden change of characteristics, or a 'shock', for which... Learn more about this topic: Mechanical Waves | Definition, Types & Examples
