Do storms impact Arctic sea ice?

As we head into the second half of August the days are noticeably shorter. That change is even more dramatic in the polar regions where the summer ice melt season is nearing its end.

This year’s melt has been particularly dramatic, with the Arctic sea-ice extent likely heading to its lowest level since satellite measurements began in 1979. The previous low extent record was set in 2012. Continue reading

What is warm rain?

Warm rain results from the joining together of a cloud’s liquid water droplets. For the rain to be warm, temperatures throughout the cloud must be above freezing, so ice particles are absent.

Rainmaking is not easy. A single, small raindrop is a collection of about 1 million cloud droplets. A typical cloud droplet is usually 10 times smaller than the periods in this article. Continue reading

Why are there so few hurricanes every year?

We are about five weeks away from the climatological peak of the hurricane season, which stretches from early June to November.

During that period, even in a particularly active year, not many hurricanes actually develop. Forming over tropical oceans ensures that warm sea-surface temperature (SST) provides a mature hurricane with a means to warm and moisten the air that flows toward the important eye-wall convection. Thus, it is not surprising that hurricanes struggle to develop if the SST is not 79.7 degrees or warmer. Continue reading

What is with the hot temperatures in Europe?

Europe recorded its hottest June ever.

The hottest temperatures occurred June 26-28, resulting from a high-pressure system that settled over Europe combined with hot winds from the Sahara Desert in Africa. France observed temperatures in excess of 113 degrees for the first time since temperatures were recorded. Continue reading

Did the moon landing influence weather forecasting?

On Saturday, we will mark the 50th anniversary of humankind’s first-ever footsteps on a different world, the lunar landing of Apollo 11.

The moon landing represented the peak of the Cold War’s space race and, though motivated by martial competition between geopolitical adversaries, the drive to reach the moon produced a large number of technical advances which most of us take for granted today. Continue reading
