[O02-P36] The Relationship between the Terrain around Minamidaira high school and the weather
Keywords:wind direction, wind speed, anemometer , a hazard slope area
On April 3, 2012, strong winds caused damage in many parts of Japan.
In adjacent Hachiouji the wind speed of 38.9m/s was observed, but Minamidaira school recorded only 12m/s.
We thought the reason the wind was suppressed in the school has something to do with the characteristics of the terrain of the school area.
So, we did a survey and research, to explore the relationship between terrain around Minamidaira high school and wind speed, using the experimental model that was created from the past wind speed data.
As a research method, we convented the data from the anemometer into a chart and summarized the characteristics of the wind that blows around school.
Tha results were compared to the wind speed data from the Japan Meteorological Agency Hachiouji-Fuchu Area to ascertain their differences and similarities
In addition we carried out a test to verify if the results were affected by the terrain.
We created a three- dimensional terrain model of the school area, and winds similar to natural conditions were applied to the model.
Also, there is a concern that the school's southest side slope might collapse.
The Slope has been specified as a hazard slope area by the Tokyo Metropalitan Government.
Therefore, we collected the rock samples on the formation of the strata, and conducted a survey to ascertain the seriousness of the dauger.
