Sea Surface

Introduction: Hurricane Katrina is the most expensive hurricane landing in the United States. An estimated 80% of New Orleans is underwater, and the authorities are reporting total damage of $ 125 billion. On August 29, 2005, this storm landed at the Saffir-Simpson storm at 31 mph per hour (Figure 1). Storm surge reached 20 feet, overturned the dam designed to protect New Orleans and reveal structural defects. Sadly, 1836 people were killed in a storm and more than 250 thousand people evacuated (Hurricane Katrina, Grohmann, etc.).

Between 1901 and 2016, the sea surface temperature increased by an average of 1.5 degrees Fahrenheit and the temperature of the tropical sea level was faster than the world average. During this century the temperature of the sea surface is expected to warm faster, which will exacerbate the tropical hurricanes. Some models predict that more storms will be Category 4 and Category 5 hurricanes, although the storm may be gone (and less storms) by the end of the century. Due to sea level rise and perhaps more intense hurricane, 39% of the US population lives in coastal areas, and many people are directly injured. According to the Intergovernmental Group 's 2014 report, the sea surface will rise from 29 to 82 cm (about 1 to 3 ft) by the end of the century, as warm planets will expand the ocean and melt the glaciers and ice sheets.

Global sea level trends and relative sea level trends are different metrics. Like the earth's undulating surface, the sea level is not flat. In other words, the sea level does not change at the same speed on a global scale. Due to a number of regional factors, sea level rise in certain places more or less than the world average, subduction, upstream flood control, erosion, local ocean current, change in ground height, and compressed weight of glacial glacier Whether the land will still rebound from

Temperature measurements on the sea and the deep sea indicate that the oceans are warming. Rise in seawater temperature causes sea level rise and thermal expansion of water. Temperature rise also means melting glaciers and sea level by adding melt water to the sea. In the last century, the sea level rose by about 1 ft, mainly due to thermal expansion of the ocean. In the next century, the sea level is expected to be close to 3 feet. In addition to loss of serious human life caused by storms in low-lying coastal countries like Bangladesh, Indian Ocean and Pacific island countries, sea level rise leads to coastal erosion, increased floods, loss of property during coastal storms Let's see.
