Key Takeaways:

Winter significantly increases Northern Hemisphere jet stream speeds and shifts its position southward, leading to more energetic weather systems and greater atmospheric instability, which contributes to various forms of turbulence.
Key aviation hazards intensify during winter, including severe icing (critical between 0 to -5°C, especially near fronts), different types of fog (radiation, advection), and powerful Atmospheric Rivers bringing widespread IMC and heavy precipitation.
Pilots must understand specific winter weather phenomena like Alberta Clippers and the implications of various precipitation types (e.g., snow, ice pellets, freezing rain) as they indicate underlying atmospheric conditions and associated flight risks, particularly severe icing.

For meteorologists, one of the big indicators that marks wintertime is the enormous increase in wind speed and atmospheric momentum in the Northern Hemisphere.

At the jet stream level, winds across the U.S. during July average about 20-40 knots, but in January these speeds rise to 60-80 knots and often much higher. This significantly increases the energy available to weather systems.
