On April 13, 2018, a huge wave suddenly appeared on the eastern shore of Lake Michigan. At the same time, next to
"We found that we could probablypredict at least a certain subset of meteotsunamis that are caused by large-amplitude atmospheric gravity waves,” said Eric Anderson, an oceanographer at NOAA Laboratory and lead author of the paper.
Meteotsunamis occur in the Great Lakes,Gulf of Mexico and Mediterranean Sea. Anderson said meteotsunamis are easier to predict than regular thunderstorms because they involve only one key variable: barometric pressure, or more specifically, dramatic changes in it. A tsunami occurs when a sudden, sudden change in air pressure hits the water, pushing it towards the shore, like a rolling pin pushing dough.
When the air moves faster or slower than the water it hits, there is no danger - the wave runs out of steam and lacks enough thrust to continue moving.
Climate change may worsen this phenomenon.Meteotsunamis have been detected on every continent except Antarctica, and a recent meeting of meteotsunami experts in Croatia has laid the foundation for a better understanding of these unique phenomena in a global context.
"With current climate forecaststhe intensity of meteotsunami is unlikely to change, but the frequency, at least in the summer, is likely to increase significantly, ”Anderson said. More convective weather conditions in late spring and early summer are more likely to catalyze such wave phenomena. According to scientists, meteotsunami are no less dangerous for people than storms. Since they cause injuries to those who spend time on the beach or on small boats.
