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。

This study has used a numerical model (RAMS) at 1 km horizontal grid intervals over the Sydney Basin to assess the impact of land cover change on storms. Multiple storms using the National Center for Environmental Prediction (NCEP) reanalysis data were simulated with pre-European settlement land cover then re-simulated with land cover representing Sydney's current land use pattern. While all si...

In this study, multi-year near-surface observations were conducted at two sites in Jakarta, Indonesia to analyse seasonal sea breeze variation. Seasonal length was defined using observed zonal wind components, the rainy season as December–March, and dry May–September. We found that Jakarta started earlier, propagated more rapidly, lasted for a shorter period of time during than season. Variatio...

In situ atmospheric observations of bromoform (CHBr3) made over a 2.5 year period at Mace Head, Ireland from May 2001Dec 2003, including during the NAMBLEX (North Atlantic Marine Boundary Layer Experiment) campaign, show broad maxima from spring until autumn and winter minima, with mixing ratios of 5.3+1.0 pptv (mid March mid October) and 1.8+0.8 pptv (DecemberFebruary). This indicates that, un...

Hourly surface meteorological measurements were coupled with surface ozone (O3) mixing ratio measurements at Hampton, Virginia and Baltimore, Maryland, two sites along the Chesapeake Bay in the Mid-Atlantic United States, to examine the behavior of surface O3 during bay breeze events and quantify the impact of the bay breeze on local O3 pollution. Analyses were performed for the months of May t...

In order to access the effect of the lakes in the atmospheric electrical field, measurements have been carried out near a large man-made lake in southern Portugal, the Alqueva reservoir, during the ALqueva hydrometeorological EXperiment 2014. The purpose of these conjoint experiments was to study the impact of the Alqueva reservoir on the atmosphere, in particular on the local atmospheric elect...
