Abstract: Common large shifts of wind direction in the weak-wind nocturnal boundary layer are poorly understood and are not adequately captured by numerical models and statistical parameterizations. The current study examines 15 ...

Abstract: The steady Reynolds stress and turbulent energy equations for steady, horizontally homogeneous mean flow are used to relate the Reynolds stress u?w? to the mean wind shear and heat fluxes in the planetary boundary layer. ...

Abstract: Steady, longitudinally invariant, barotropic, boundary layer flow is numerically studied at low latitudes where advective accelerations may he large and the Coriolis parameter is small. Flow is generated by specifying the ...

Abstract: The influence of advective accelerations in the low-latitude boundary layer and coupling between this boundary layer and the free atmosphere are numerically examined for steady longitudinally invariant flow. Pressure ...

Abstract: ature is wild, unconstrained, and often dangerous. In particular, studying air?sea interaction in winds typical of tropical cyclones can place researchers, their instruments, and even their research platforms in jeopardy. ...

Abstract: rom almost 7000 near-surface eddy-covariance flux measurements over the sea, the authors deduce a new air?sea drag relation for aerodynamically rough flow:Here u* is the measured friction velocity, and UN10 is the ...

Abstract: he 10-m neutral drag coefficient (CDN10) over the sea is calculated using a large observational dataset consisting of 5800 estimates of the mean flow and the fluxes from aircraft eddy-covariance measurements. The dataset ...

Abstract: Rawinsonde observations taken during the National Hail Research Experiment are analyzed by multiple-linear regression techniques to study the influence of environmental factors on hailstorm severity. The latter is inferred ...

Abstract: ver 5000 aircraft eddy-covariance measurements from four different aircraft in nine different experiments are used to develop a simple model for the friction velocity over the sea. Unlike the widely used Coupled Ocean?Atmosphere ...

Abstract: This study examines the spatial variation of the wind field observed in the coastal zone of southeast Korea with its complex terrain, using measurements from a regional network 75 km across and centered about Busan. Results ...
