300-year-old tree rings confirm recent uptick in hurricane-driven rainfall

Tropical cyclones like Hurricane Ida can cause severe flooding, producing disruptions, damage, and loss of life. Like many other types of weather, tropical cyclones and hurricanes on the US East Coast have become more extreme over the past several decades. Although there is some controversy over the extent of the increase in intensity, there is evidence that such storms are moving more slowly than in the past. This slower movement causes storms to last longer and produce more rain. However, because conventional weather records only go as far back as 1948, it’s unclear how unusual these slow-moving cyclones are compared to earlier weather patterns. 

A recent study addresses this question by using tree rings to reconstruct hundreds of years of seasonal cyclone precipitation levels. The studied trees, some over 300 years old, show that precipitation extremes have been increasing by 2 to 4 mm per decade, resulting in a cumulative increase in rainfall of as much as 128 mm (five inches) compared to the early 1700s. The greatest increases have occurred in the last 60 years, and recent extremes are unmatched by any prior events. 

Beyond establishing these reconstructed historical records, researchers are working with these data sets to improve forecasts of what this region might expect in the future.

Europe’s July floods: So rare and extreme, they’re hard to study

The backdrop of a steadily warming climate has frequently raised questions about whether any given extreme weather event could have been influenced by climate change. It’s a natural question to ask, but answering it in peer-reviewed detail usually takes months or years. In response, researchers started the World Weather Attribution program, which has developed a streamlined analysis pipeline that lets them address questions of climate influence before the public has forgotten the event happened. This technique allowed the group to rapidly determine that climate change played a key role in this summer’s Pacific Northwest heat wave.

Now, the group has attempted to tackle this summer’s European floods, which destroyed communities in Germany, Belgium, and the Netherlands. And here, the answer was a lot more complicated. The floods hit a small area and were extreme enough that they destroyed some of the monitoring equipment that would otherwise have told us just how bad they were. Nevertheless, the team found the climate change likely boosted the chances of an event like that in northwestern Europe.

When the rains came

The weather pattern that produced the rain wasn’t particularly exceptional, and it consisted of a low-pressure system that parked over Europe for a couple of days. The warm, moisture-rich air this drew from the Mediterranean ended up rotating around the low pressure. The Mediterranean air crossed a number of ranges of low hills in northwestern Europe, which caused the sort of atmospheric disruptions that trigger rainfall for a couple of days.
