We investigated organic molecular compositions of summertime aerosols collected at the summit of Mt. Fuji (3776 m a.s.l.) in July-August 2009. More than 120 organic species were identified using GC/MS. Concentrations of both primary and secondary organic aerosol (SOA) tracers in whole-day samples were 4-20 times higher than those in nighttime samples, suggesting that valley breeze is an efficie...

The lexical status of multiword expressions (MWEs), such as make a decision and shoot the breeze, has long been a matter of debate. Although MWEs behave much like phrases on the surface, it has been argued that they should be treated like words because their components together form a single unit of meaning. However, MWEs are not a homogeneous lexical category, but rather can have distinct sema...

Wind energy development has been limited by concerns associated to the varying features in wind speed which tends destabilize power system. This study aims clarify variability of winds within a day Philippines, specifically hourly changes onshore horizontal at 100-m hub-heights. A whole one-year experiment using Weather Research and Forecasting model shows that speeds decrease during transition...

Extreme heat weather events have received increasing attention and has become of special importance as they can remarkably affect sectors as diverse as public health, energy consumption, water resources, natural biodiversity and agricultural production. In this regard, summer temperatures have become a parameter of essential interest under a framework of a hypothetical increase in the number of...

本稿では，岩石や水の重要な物性である比熱について，簡易に測定可能な実験方法を開発し，試行実践を行った。その結果，水については，理論値よりも過大評価される傾向があったが，岩石については，ほぼ妥当な値を得ることができた。海陸風や季節風の成因を理解するためには，岩石と水の比熱が大きく異なることを理解することが非常に重要である。本稿の方法では具体的に水と岩石の比熱を得ることができ，岩石と水では4倍前後の比熱の違いがあることを理解するために十分な結果が得られた。

Abstract The physical hydroclimate system of the Amazon functions on several spatial and temporal scales. Large-scale processes control main seasonal patterns atmospheric circulation rainfall. Seasonal variability in solar forcing, associated with low rainforest albedo, provides energy for continental heating, convection, onset South American monsoon. Mesoscale cause localized circulations such...
