Abstract Sea-breeze front (SBF) intruding coastal cities can lead to sudden changes in local weather and air quality. Its structures and disturbances over the urban surface with dense tall buildings have been a challenge for numerical modeling. In this study, we present the fine-scale structures of an actual SBF simulated by mesoscale-to-LES models at 3-meter resolution in a 15-km domain of Sendai City, Japan. The head of SBF is shown to develop remarkable three-dimensional structures in the downtown area where it interacts strongly with the microscale turbulent flows induced by buildings. Localized strong updrafts form at the lees of high-rise buildings within a few minutes just after the passing SBF, as ejections emerge in urban warm airmass surrounded by the cool airmass of sea breeze. Downdrafts in sea breeze are seen at the windward sides of high-rise buildings and help to increase wind speed in adjacent streamwise streets. After the passage of SBF, near-surface wind speed exhibit high-frequency fluctuations with a period of 2–3 minutes, in good agreement with in-situ observations in downtown area. These results demonstrate the good capabilities of the building-resolving LES of both mesoscale weather conditions and microscale turbulent flows over a large city for the prediction of urban weather and environment in the streets.

Abstract This study evaluates a parameterization scheme for subgrid-scale (SGS) fluxes based on the scale-similarity assumption and employing a large-eddy simulation of an idealized back-building convective system. In this parameterization, the SGS fluxes are decomposed into the “Leonard term,” which depends only on the resolved scale components, the “Reynolds term,” which depends only on the SGS components, and the “cross term,” which corresponds to the interaction between the resolved scale and SGS components. Assuming a linear relationship between the Leonard term and the Reynolds and cross terms, SGS fluxes are expressed as the product of an empirical coefficient and the Leonard term. The Leonard term reasonably represents the SGS flux derived by a smooth filter operation, including the countergradient vertical SGS transport of potential temperature, which cannot be represented by a traditional eddy-diffusivity model. The dependence of the empirical coefficient on filter width is also evaluated. This dependence is related mainly to the Reynolds term, the magnitude of which varies widely with the filter width. The estimation based on the spectral decomposition of the Reynolds term explains the obtained dependence of the empirical coefficient for the vertical flux on filter width. In contrast, the variation of the empirical coefficient with filter width is not required to obtain the horizontal flux. For the parameterization of SGS fluxes in kilometer-scale models that use finite difference or volume methods, the Leonard term is expressed by the horizontal gradient of variables on a discrete grid. The Leonard term on a discrete grid also accurately represents the amplitude and spatial pattern of the SGS flux. Significance Statement Kilometer-scale numerical weather prediction models can reproduce deep convection explicitly. However, they cannot reproduce smaller inner structures within this deep convection. Therefore, a parameterization scheme that can express the nature of the transport associated with such structures is required. Using a large-eddy simulation with a horizontal resolution sufficient to express such inner structures, we evaluated a parameterization based on the scale similarity assumption, including an empirical coefficient. Based on spectral decomposition, we quantitatively estimated the relationship between the empirical coefficient and grid spacing. Our results provide guidance in selecting the value of the empirical coefficient in this parameterization.

Abstract A heavy rainfall event caused by mesoscale convective systems (MCSs) resulted in flooding over areas of Davao City in Mindanao Island, Philippines, on 03 May 2017. The event occurred during the summer season (April–May) under weak large-scale conditions. This study investigated the initiation and development of MCSs by performing high-resolution numerical simulations with the finest grid spacing of 200 m, using the Weather Research and Forecasting (WRF) model. It was found that the merging of two meso-$$\beta$$ scale convective systems over the west and east of Mount Apo caused the flood-producing rainfall in the Davao area. Results show that the west meso-$$\beta$$ scale convective system formed over the basin area in Mindanao Island due to moisture advection from sea breeze circulation. In addition, the concave geometry of the Mindanao basin assisted in accumulating moisture which made the basin favorable for convection development. Meanwhile, the precipitating downdrafts generated cold pools wherein the continuous convergence of multiple outflow boundaries resulted in the further development and maintenance of the MCS over the basin. While the east meso-$$\beta$$ scale convective system developed over the Davao area due to the interaction between southeasterlies (ambient trade winds) and Mount Apo terrain. Merging of the MCSs resulted in the development of a larger meso-$$\beta$$ scale system. Eventually, the larger meso-$$\beta$$ scale convective system split and splitted MCSs weakened over time.

<jats:title>Abstract</jats:title> <jats:p>In this study, a clear-air turbulence event was reproduced using a high-resolution (250 m) large-eddy simulation in the Weather Research and Forecasting (WRF) Model, and the resulting wind field was used in a flight simulation to estimate the vertical acceleration changes experienced by an aircraft. Conditions were simulated for 16 December 2014 when many intense turbulence encounters (and one accident) associated with an extratropical cyclone were reported over the Tokyo area. Based on observations and the WRF simulation, the turbulence was attributed to shear-layer instability near the jet stream axis. Simulation results confirmed the existence of the instability, which led to horizontal vortices with an amplitude of vertical velocity from +20 to −12 m s<jats:sup>−1</jats:sup>. The maximum eddy dissipation rate was estimated to be over 0.7, which suggested that the model reproduced turbulence conditions likely to cause strong shaking in large-size aircraft. A flight simulator based on aircraft equations of motion estimated vertical acceleration changes of +1.57 to +0.08 G on a Boeing 777-class aircraft. Although the simulated amplitudes of the vertical acceleration changes were smaller than those reported in the accident (+1.8 to −0.88 G), the model successfully reproduced aircraft motion using a combination of atmospheric and flight simulations.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Record-breaking precipitation due to a back-building convective system occurred in Kyushu Island, Japan, on 5 July 2017. In this paper, a quasi-stationary back-building convective system is reproduced using a regional weather prediction model initialized with a single representative sounding in which the land–sea distribution around the observed convective system is crudely simplified. The simulated convective system and heavy precipitation are reasonably similar to observations. Horizontal resolution finer than 1 km is found to be necessary for reproducing the convective system. The area of heavy precipitation tends to shift downstream with finer horizontal resolution. The surface temperature contrasts at the northern and southern coastlines cause sea breezes and a stationary convergence line between them continuously triggers cumulus clouds. The horizontal convergence near the surface is further enhanced by preceding cumulus clouds that cause the latent heating aloft and generate a mesoscale surface pressure depression. Vertical shear of the environmental wind is also found to be important for organizing the convective system but veering of its wind direction and a cold pool are not essential.</jats:p>

This study aims to examine whether an ultra-high resolution numerical weather prediction (NWP) model with a large domain is able to produce more accurate forecast. The following three factors of NWP were investigated: (1) grid spacing, (2) turbulence closure model (Mellor-Yamada-Nakanishi-Niino [MYNN] level 2.5 and 3, and Deardorff [DD]), (3) terrain data. The turbulence closure model greatly influenced to the position of the front and associated rain band. In the experiments with DD, the front was simulated at the similar position to observation, while in the experiments with MYNN the front was shifted to the northwest of the island. The 250-m grid model with the finest terrain representation showed the best performance in all experiments. These results demonstrate that the very high resolution NWP model with the large domain has the ability to better predict the meso-b scale rain band and associated precipitation.

Dust devils are small-scale vertical vortices that often occur in the lower atmosphere when a convective mixed layer develops. A large eddy simulation of dust devils is used to study the source of their strong vertical vorticity. A backward tracking of a material surface that flows into a dust devil and an analysis of a circulation in the material surface show that stretching of small vertical vorticity associated with the circulation near the surface leads to form dust devils. Significant circulations with which dust devils can be generated prevail in a convective mixed layer and are likely to be derived by tilting of horizontal vorticity at the middle of the convective mixed layer. An additional study on the effects of ambient rotation on dust devils also supports above findings.

Dust devils are small-scale vortices that often occur in the atmosphere when a convective mixed layer develops due to a strong heating from the ground. Several mechanisms for generating vertical vorticity in dust devils have been suggested, but have not been clarified yet. In this paper, a large eddy simulation of dust devils is used to study the source of the vertical vorticity through a backward-trajectory analysis that examines the vorticity budget and temporal variation of a circulation for a particular material surface. The results of the analyses show that horizontal vorticity generated baroclinically in a downdraft region plays a critical role for generating vertical vorticity.

This study has elucidated many new features of convective clouds. Major findings are the clarification of the actual condition of convective clouds, the formation and maintenance mechanism of a line-shaped precipitation system by organization of cumulonimbus clouds, the occurrence mechanism of severe phenomena, and a development of novel approach of short-range forecast of 1-minute precipitation amount by an ensemble of an advanced three-dimensional wind synthesis over a complex terrain, high-resolution numerical model experiments, polarization radar analysis, and a non-linear time series analysis. In particular, it is notable that a success of the elucidation of the time evolution of three-dimensional structures of convective clouds at a very high temporal resolution of 30 seconds by employing dual-Doppler wind synthesis that uses two cutting-edge phased array weather radars. Many of these accomplishments are published in peer reviewed papers and in conference presentations.

When turbulent eddies are partially resolved in a numerical weather prediction model (i.e. large eddy simulation), the conventional parametrization of the surface layers are inadequate. How a surface layer parametrization should be in such a model is investigated by sensitivity experiments with a large eddy simulation, direct numerical simulation of turbulence, and wind tunnel experiments. We have also studies surface layer processes specific to the strong stable and unstable conditions.
