Meteorology
Disasters occur every year in Japan due to heavy rain caused by meiyu fronts, typhoons, and linear precipitation bands. In fact, data shows that the frequency of heavy rain has increased in the past few decades, and this is predicted to continue to increase in the future, due to global warming. Along with rain, wind, especially sudden strong winds (gusts), causes great damage. In addition to damaging moving cars and buildings, gusts can also overturn ship cargo and damage wind power generators, causing significant damage. Generally, there is a proportional relationship between wind strength and rainfall, and when strong winds blow, it often rains heavily. As the frequency of heavy rains is increasing due to global warming, there is a possibility that the frequency of gusts of wind is also increasing, which this project will examine. Topography plays a large role in determining the wind. Therefore, in order to analyze wind gusts, a location that is affected by both complex topography and the sea is desirable. Therefore, in this project, we will carry out observations on Awaji Island and collect data from the past several decades, as it has the characteristics of both the topography and islands of the Seto Inland Sea and has a wealth of observation data that is constantly being measured by radar.
