Micrbaroms and Hemmingway

June 12, 2018

Microbaroms are infrasound signals created by certain kinds of ocean waves that are captured thousands of miles away. The Journal of Geophysical Research-Oceans reported that these signals, delivered during tropical cyclones, can be distinguished from other wave activity.  Microbaroms are an asset in monitoring and predicting wave hazards during hurricanes.  In 2009, researchers monitored two Pacific tropical cyclones, Niki and Felicia that moved over an infrasound sensor in Hawaii.  They determined that the microbaroms from the hurricane activity overwhelmed weaker signals from similar ocean activity. It represented the first step in using infrasound measurements to determine storm strength. Recently,  additional experimentation examined world-wide storms for comparative large-scale weather patterns.

 

In closing, Hurricanes Katrina, Andrew, Gustav, Rita, Camille and Betsy often become the comparative storms. Another storm was chronicled in an interesting book entitled, “Hemingway’s’ Hurricane: The Great Florida Keys Storm of 1935” by Phil Scott.  It’s called Hemingway’s Hurricane because the famous author lived 80 miles southwest of Key West where he rode out the storm and journaled his experiences from August 30 to September 4, 1935.  Scott’s angle on the book includes the lives of 700 World War I veterans who relocated to Florida in 1935 under the Federal Emergency Relief Organization to assist in public works projects. The storm hit three veteran’s camps causing more than 400 deaths when early evacuations could have saved their lives.
