In meteorology, a cyclone is an area of closed, circular fluid motion rotating in the same direction as the Earth. This is usually characterized by inward spiraling winds that rotate counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere of the Earth. A "tropical cyclone" is a synonym for a hurricane. Most large-scale cyclonic circulations are centered on areas of low atmospheric pressure. The largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale. Warm-core cyclones such as tropical cyclones, mesocyclones, and polar lows lie within the smaller mesoscale. Subtropical cyclones are of intermediate size. Upper level cyclones can exist without the presence of a surface low, and can pinch off from the base of the Tropical Upper Tropospheric Trough during the summer months in the Northern Hemisphere. Cyclones have also been seen on extraterrestrial planets, such as Mars and Neptune.

Cyclogenesis describes the process of cyclone formation and intensification.Extratropical cyclones form as waves in large regions of enhanced mid-latitude temperature contrasts called baroclinic zones. These zones contract to form weather fronts as the cyclonic circulation closes and intensifies. Later in their life cycle, cyclones occlude as cold core systems. A cyclone's track is guided over the course of its 2 to 6 day life cycle by the steering flow of the cancer or subtropical jet stream.

John M. "Johnny" Orr (born June 10, 1927) is a retired American basketball player and coach, best known as the head coach of men's basketball at the University of Michigan and at Iowa State University.

Orr was born in Yale, Kansas. He grew up in the central Illinois town of Taylorville during the Great Depression. Orr attended Taylorville High School under coach Dolph Stanley and in his senior year (1944) led the Tornadoes to a state championship and a 45–0 record, the first team to ever finish a season undefeated in the Illinois High School Association's history. In 2007, Orr was voted one of the "100 Legends of the IHSA Boys Basketball Tournament," recognizing his superior performance in his appearance in the tournament. After high school Orr went to the University of Illinois and was the youngest freshman to compete in three sports. After joining the United States Navy for the end of World War II, Orr returned to the college game at Beloit College. This reunited him with his high school coach Dolph Stanley, who had came to Beloit College as athletic director, head basketball and football coach.
