We've all experienced sweltering summer days that make us want to seek refuge in the air conditioning.

A heat dome occurs when a persistent region of high pressure traps heat over an area. The heat dome can stretch over several states and linger for days to weeks, leaving the people, crops and animals below to suffer through stagnant, hot air that can feel like an oven.

To comprehend El Niño, we must first acknowledge its counterpart, La Niña, and their intricate relationship as part of the El Niño Southern Oscillation (ENSO) system.

Every two to seven years, the equatorial Pacific Ocean gets up to 3°C warmer (what we know as an El Niño event) or colder (La Niña) than usual, triggering a cascade of effects felt around the world.

The U.S. recently has experienced two rarer events: organized lines of thunderstorms with widespread damaging winds, known as derechos.

John Oliver discusses the tension between the public and private worlds of predicting the weather.
