A forecast system to predict wind power ramps was developed and applied to evaluate the similarity between sea level pressure (SLP) patterns in global-scale model forecasts and weather patterns associated with abrupt wind speed changes. The settin...

<p>&emsp;This study numerically examined how the locally strong "Karakkaze" wind in the Kanto Plain of Japan is affected by terrain shape, particularly by a convex feature in the mountain range. Our method involved running idealized numerical simu...
SOLA   advpub    2019
<p>This study revealed that the Karakkaze events accompanied by rising temperature are more frequent than those accompanied by dropping temperature. This finding contrasted with the general belief for many years that the Karakkaze is a bora-type l...

<p>We quantitatively evaluated the contributions of foehn winds and the urban heat island (UHI) effect to an extreme high-temperature nocturnal event at Niigata city on 23-24 August 2018. During this event, southeasterly winds blew continually acr...
