Does Climate Change Effect How Hail Forms?

The Nature Climate Change publication conducted a study that reveals in the second half of this century, the United States will experience fewer days of hail storms but for the hail storms that do happen, the hail stones will be much larger. Experts say hailstones larger than baseballs are very possible.

These predictions are not easy to determine just as global warming isn’t an exact science. Researchers used multiple weather models to simulate how hai might form and increase in size between the years of 2041 and 2070 if climate change continues to accelerate.

The US areas most affected will be eastern Colorado, Nebraska, and southern South Dakota.

How Climate Change Can Affect Weather Trends

 Does climate change really affect the weather? Environmental experts say yes.

  • Water vapor. The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth’s atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.
  • Warming Air. Warmer conditions will probably lead to more evaporation and precipitation overall, but individual regions will vary, some becoming wetter and others drier.
  • Air Pollution. Air pollution hugely increases the size of hail, and thus the amount of damage it can cause to crops and personal property.  The hail inside clouds formed in the dirty air starts at higher levels and fall through the whole cloud, collecting droplets along the way. The result are rock-like ice stones about 10 times the mass of hail formed in clean, pollution-free clouds. The kinetic energy — that is, the force of impact — of hail falling on the surface from dirty clouds was 30 to 50 times higher.
