A Prediction: It’s Gonna Be Hot

March 30, 2016

We’ve become much better in recent years at predicting storms and other weather events. Even for hurricanes, which can change intensity and direction unpredictably, scientists can give a fairly good idea of what will happen nearly a week before it does, thanks to better satellite data and more sophisticated models, and NOAA makes that information available in real time. This article from Stormwater looks at how scientists in Taiwan and elsewhere are using new techniques to predict local rainfall patterns during massive storms like hurricanes—or typhoons, as they’re more commonly known in the Pacific.

Now researchers are looking at ocean water temperatures to make an even more long-term weather prediction. Specific temperature patterns in the northern Pacific Ocean can show that a heat wave is likely to occur in the Midwestern or Eastern US as much as 50 days later. That’s weeks beyond what we’ve been able to predict before.

Why is that important? Hurricanes and floods aren’t the only weather events that can kill; on average more than 600 people die each year in the US from heat-related causes, and even more during especially intense heat waves. Heat waves also take a toll on crops and livestock. With more time to plan, urban officials could set up more shelters or cooling centers, and social workers could arrange to check on homebound, chronically ill people, who tend to be hit hard by extreme temperatures, especially in parts of the country where air conditioning is less common. Farmers could arrange shade for animals and extra irrigation.

A study on the phenomenon was recently published in Nature Geoscience and is summarized here. Scientists examined more than three decades of data to chart the correlation between ocean temperatures and inland heat waves. Although they aren’t sure exactly what the connection is between the two, one of the study’s authors theorizes that ocean temperatures affect the jet stream, which in turn causes high-pressure air to settle over parts of the US.

Hydraulics 101 (for Those Who Skipped It in College)

At a loss when hydraulic engineers start talking? Join former IECA president David Williams to learn to “talk the talk” and better understand your hydraulic engineers and their reports when they’re talking in terms of unsteady flow, allowable sheer stress, Manning’s “n,” etc. In this second part of our Surface Water Master Class series, Williams presents a live and on-demand two-session webinar, where he’ll discuss the base concepts, terms, and analyses behind hydraulics and hydraulic studies, as well as advanced topics (e.g., hydraulic scour of structures, weirs, culverts, hydraulic grade control, and bank stabilization), and how all of these are essential for effective hydraulic design.
