Planet Disco's unusual weather patterns are influenced by several forces:

The planet's flattened disc shape results in sunless winters in the extreme latitudes. Disco's extended year (622 earth days) brings long seasons and contributes to extreme winter temperatures.













The planet's rapid rotational speed exacerbates high wind conditions and results in frequent tornadoes.





Disco's rapid rotation speeds up ocean currents, undersea volcanic venting results in warm ocean temperatures, and geologic movement causes frequent large waves (tsunamis).








Climate

Disco's temperatures range extremely according to latitude and season. The bulk of Disco's land mass lies in the planet's equatorial region. This area receives year-round temperate conditions in the 25 degrees Celsius range. Air temperatures above the polar oceans are moderate (20-25 degrees Celsius) in the summer time but frigid in the long, sunless winter (-20 degrees Celsius average). Although polar air temperatures remain cold during the long winter months, ice caps do not form and water temperatures remain moderate (15 degrees Celsius) due to undersea thermal venting. Disco's atmosphere of largely Nitrogen and Oxygen help retain the sun's heat and a gaseous layer similar to Earth's Ozone layer helps filter out ultraviolet rays and protect life from dangerous radiation.



Precipitation and Storms

Equatorial land areas receive steady rainfall with regular thunderstorms year-round. Rainfall in mountain regions can average 150" annually. Trade winds that blow in this region are stronger than on earth due to the planet's rapid rotational speed. Coastal regions at the northern and southern latitudes experience severe weather by contrast. As winter arrives, the hemisphere facing away from the sun receives no direct sunlight, being shaded by the edge of the planet's disc shape. The result is a long freeze cycle on the land distant from the equator. The polar oceans, warmed from thermal venting, send water vapor rising which quickly condenses in the cold winter air to send violent storms toward the coastline. Driving rain, sleet and snow with gale force winds are common during winter in these regions. Tornadoes are frequent visitors also. As if this weren't enough, active undersea land plates cause frequent earthquakes which shake the land and send forth giant destructive waves (tsunamis). Precipitation over the polar oceans averages a moderate 20" annually.
