@article{Hiroki Nishiwaki_Hiroyuki Ii_2020, title={RELATIONSHIP BETWEEN RAIN CLOUDS DIRECTION, TOPOGRAPHY AND AMOUNT OF PRECIPITATION IN BETWEEN THE OSAKA PLAIN AND THE SOUTH IKOMA MOUNTAINS, MIDDLE OF JAPAN}, volume={18}, url={https://geomatejournal.com/geomate/article/view/339}, abstractNote={<p><br>The area between from the Osaka Plain to the Ikoma Mountains faces sea at only west direction <br>and is surrounded by mountains at the other directions. Then, rain clouds can directly encounter the Ikoma <br>Mountains only from west direction before crossing any mountains. On the other hand, rain clouds cannot <br>encounter the Ikoma Mountains from the other directions before crossing surrounding mountains. Only when <br>rain clouds migrated from west direction, amounts of precipitation in the Ikoma Mountains were observed to <br>be 41 % higher than in the Osaka Plain. The altitude difference between both areas is about 400 m. When rain<br>clouds migrated from the other directions, both amounts of precipitation for the Ikoma Mountains and the <br>Osaka plain were almost the same. Therefore, altitude effect of amounts of precipitation for foot of mountain <br>and top of mountain was observed only when rain clouds directly encountered the mountain before crossing <br>the other mountains. </p>}, number={65}, journal={GEOMATE Journal}, author={Hiroki Nishiwaki and Hiroyuki Ii}, year={2020}, month={Jan.}, pages={34–40} }
