Sea breeze: Induced mesoscale systems and severe weather [PDF]

Sea-breeze-deep convective interactions over the Florida peninsula were investigated using a cloud/mesoscale numerical model. The objective was to gain a better understanding of sea-breeze and deep convective interactions over the Florida peninsula using

Parameterization of Vertical Profiles of Governing Microphysical Parameters of Shallow Cumulus Cloud Ensembles Using LES with Bin Microphysics

Journal of the Atmospheric Sciences, 2019
Shallow convection is a subgrid process in cloud-resolving models for which their grid box is larger than the size of small cumulus clouds (Cu). At the same time such Cu substantially affect radiation properties and thermodynamic parameters of the low ...

Generalized Task‐Driven Design of Soft Robots via Reduced‐Order Finite Element Method‐Based Surrogate Modeling

Advanced Intelligent Systems, EarlyView.
A unified, reusable modeling pipeline enables task‐driven design of soft robots across actuator families and task scenarios. High‐fidelity simulations are compressed into compact pseudo‐rigid‐body joint surrogates, while a design‐conditioned meta‐model generates new surrogates from geometry parameters without rerunning finite element method.

Sensitivity of WRF model parameterizations in simulating extreme rainfall over complex terrain – case of July 2020 over the Poyang Lake basin, China

Geomatics, Natural Hazards & Risk
In recent years, the Weather Research and Forecasting (WRF) model has been used to obtain reliable rainfall with higher spatial and temporal resolutions. The selection of physical parameterization schemes largely influences the WRF simulation.

Lost in aggregation? On the importance of local food price data for food poverty estimates

American Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Effect of Spatial Resolution and Cumulus Parameterization on Simulated Precipitation over South Asia

, 2016
This paper evaluates the ability of a regional-scale climate model to simulate precipitation over the South Asian tropical region. Experiments were conducted using three different spatial resolutions, with and without cumulus parameterization (CP), to ...

Diurnal cycles of Mei-yu rainfall simulated over eastern China: Sensitivity to cumulus convective parameterization

Atmospheric research, 2018
Realistic simulation of the diurnal cycle of rainfall has been regarded as one of the challenging issues. This study investigates the sensitivity of simulating the diurnal cycle of Mei-yu rainfall over eastern China to cumulus parameterization schemes ...

A leaf phenomics approach for estimating belowground traits in North American licorice

American Journal of Botany, EarlyView.
Abstract Premise Selective breeding over thousands of years has prioritized aboveground yield, with little regard for changes belowground. Roots underpin plant growth and resilience, but our knowledge of these critical structures lags behind that of aboveground structures.

An Ensemble Cumulus Convection Parameterization with Explicit Cloud Treatment

Journal of the Atmospheric Sciences, 2010
AbstractThe paper describes a convection parameterization employing a new formulation of the quasi-equilibrium closure hypothesis of Arakawa and Schubert. The scheme models a full spectrum of different cumulus clouds and its evolution within one time step of the host global climate model.
