Air Mass Formation andMovement
Continental interiors act source regions for distinct air masses. In wintenr, thee long, dark nights andd snow- covered ground allow air to cool radiatively.

Latitude andd Solar Radiation
The Angle of Incoming Solar Radious
Latitude determinas the angle at t which sunlight strikes the Earth 's surface. At higher latigedes, near the poles, sunlight arrives at a lower angle, spreading it energy over a larger surface area. This reduces the intensity of solar heating per unit area. During winter in thee Northern Hemisphere, thee low angle of thee sun combinad with short day entiths means that hightendre continentaintaintail regions reces receivee very litte solte.

Earth 's axial tilt of approximately 23.5 degrees amplifies seafies differences in solar radiation, especially at higher lamorandes. During summer in thee Northern Hemisphere, thee North Pole is tilted toward then sun, resutting in more direct sunlight and longer days.
