In summary, cold air is less conducive to the formation of lightning due to its lack of energy and the requirement for strong updrafts in the formation of cumulonimbus clouds. The freezing and thawing of airborne water also plays a role in charging the cloud. While it is possible for lightning to occur during a snowstorm, it is a rare event due to the dampening effect of cold air on moisture.

Why is there never thunders during winters? Shoudnt the cold air be even more conductive?

Cold air is less energetic. The process by which lightning is generated is not yet fully understood, but it does seem to require a lot of energy. For one thing, lightning only seems to come from cumulonymbus clouds, those big, tall clouds with the "anvil-shaped" tops that you allways see in association with thunderstorms. The formation of these clouds requires strong updrafts, which are very seldom found in cold air. And the storm itself is certainly a very energetic process.

There is also some evidence that te alternate freezing and thawing of the airborn H2o plays a role in charging the cloud.


P.S.
I have heard that lightning can come from a snowstorm, it's just a very rare event.

just an aside, but here in the uk we had snow storms last week which had lightning in them.

Live in Canada, have experianced both...

EDIT yes it is a rare thing, the cold apparently 'dampens' things, cold air holds less moisture...the reasoning behind the "It Never snows when it is really reeally cold" (falacy) cause it can, but it is 'more rare', produces some really nice snow though, "Champagne" Snow, crosscountry skied in it, beauty!

1. What are winter thunderstorms?

Winter thunderstorms are a type of storm that occurs during the winter season, typically characterized by the presence of lightning, thunder, and heavy precipitation. Unlike summer thunderstorms, which are fueled by warm, moist air, winter thunderstorms are fueled by strong temperature contrasts in the atmosphere.

2. How do winter thunderstorms form?

Winter thunderstorms form when warm, moist air from the Gulf of Mexico collides with cold, dry air from the Arctic. This collision of air masses creates instability in the atmosphere, leading to the formation of thunderstorms. Additionally, strong upper-level winds and steep temperature gradients can also contribute to the development of winter thunderstorms.

3. What makes winter thunderstorms unique?

Winter thunderstorms are unique because they occur during a season that is typically associated with cold and snowy weather, rather than thunderstorms. This makes them rare and often more intense than summer thunderstorms. Additionally, winter thunderstorms can produce a variety of precipitation types, including snow, sleet, and freezing rain.

4. Are winter thunderstorms dangerous?

Yes, winter thunderstorms can be dangerous due to the potential for lightning strikes, strong winds, and heavy precipitation. They can also create hazardous road conditions, especially if the precipitation turns into ice. It is important to take precautions during winter thunderstorms, such as staying indoors and avoiding contact with electrical devices.

5. How can scientists study winter thunderstorms?

Scientists study winter thunderstorms using a variety of tools, including radars, satellites, and weather balloons. These instruments help them track the formation, movement, and intensity of winter thunderstorms. Researchers also use computer models to simulate and better understand the processes that drive winter thunderstorm development.
