The temperature of the World Ocean has a major impact on rainfall: The warmer the surface of the ocean the stronger the tropical storms and cyclones (hurricanes, typhoons) across the globe. Expendable Bathythermograph (XBT) is a probe used since 1955 for ocean thermal profile observations at different depth in the ocean. Using data provided by XBT probes and innovative Argo profiling floats, Levitus et alt. published a research article updated in 2012, which unveiled a substantial increase in Ocean Heat Content (OHC) since 1955 to 2010. https://www.nodc.noaa.gov/OC5/3M_HEAT_CONTENT/ The relevance of Levitus’ research, led the scientific community to thoroughly analyze the 1955-2010 series of XBT data and methods used to measure the temperature of the World Ocean. The Science Workshop held in Tokyo in October 5-7, 2016 concluded that it was more accurate to use the corrected XBT data series published by Chen et alt. in 2016 and that Ocean Heat Content (OCH) should be a fundamental metric to assess models. The following figure depicts an OCH long term trend since 1970 to 2010 showing a very revealing fact: All the oceans are warming. The increase of temperature provides additional energy to monster storms that hit U.S.A., India, China and other countries.
So what to do? The construction code in South Florida, U.S.A. had significant changes after hurricane Andrew in 1992, so new buildings were prepared to withstand hurricane force winds. https://www.businessinsurance.com/article/20120819/NEWS06/308199985 Also in places near rivers or in the beach such as in the State of Louisiana, U.S.A. prone to flash flooding or coastal storm surges, some houses are built on elevated stilts or platforms. https://makewealthhistory.org/2016/01/08/five-ways-to-build-a-flood-proof-home/ Comments are closed.
