Investigating the Causes and Impacts of Convective Aggregation in a High Resolution Atmospheric GCM

Journal of Advances in Modeling Earth Systems, 2021
A ∼50 km resolution atmospheric general circulation model (GCM) is used to investigate the impact of radiative interactions on spatial organization of convection, the model's mean state, and extreme precipitation events in the presence of realistic ...

A single scaling parameter as a first approximation to describe the rainfall pattern of a place: application on Catalonia [PDF]

, 2018
As well as in other natural processes, it has been frequently observed that the phenomenon arising from the rainfall generation process presents fractal self-similarity of statistical type, and thus, rainfall series generally show scaling properties ...

The environment of aggregated deep convection

Journal of Advances in Modeling Earth Systems, 2017
AbstractIn this study, the environment of aggregated deep convection is investigated using a vector vorticity equation cloud‐resolving model (VVM). Idealized experiments are performed under various environmental moisture with or without imposed vertical wind shear.

A budget for the size of convective self‐aggregation [PDF]

Quarterly Journal of the Royal Meteorological Society, 2019
There is no consensus on the physical mechanisms controlling the scale at which convective activity organizes near the Equator. Here, we introduce a diagnostic framework relating the evolution of the length‐scale of convective aggregation to the net radiative heating, the surface enthalpy flux, and horizontal energy transport.

Convectively generated gravity waves and convective aggregation innumerical models of tropical dynamics

, 2018
In this dissertation I investigate two phenomena, which both arise from atmospheric moist convection: on the one hand, the gravity waves emanated from convection and on the other hand convective aggregation. Convectively generated gravity waves are investigated on novel spatial and temporal scales. We use numerical models that display the transition of

Sensitivity of the Horizontal Scale of Convective Self‐Aggregation to Sea Surface Temperature in Radiative Convective Equilibrium Experiments Using a Global Nonhydrostatic Model

Journal of Advances in Modeling Earth Systems, 2022
We conduct radiative convection equilibrium experiments using a global nonhydrostatic model to investigate the dependence of convective self‐aggregation (CSA) on domain size and sea surface temperature (SST).

A photonic crystal cavity-optical fiber tip nanoparticle sensor for biomedical applications

, 2012
We present a sensor capable of detecting solution-based nanoparticles using an optical fiber tip functionalized with a photonic crystal cavity. When sensor tips are retracted from a nanoparticle solution after being submerged, we find that a combination ...

Tropical Cyclone Intensity Estimation Using Multi-Dimensional Convolutional Neural Networks from Geostationary Satellite Data [PDF]

, 2019
For a long time, researchers have tried to find a way to analyze tropical cyclone (TC) intensity in real-time. Since there is no standardized method for estimating TC intensity and the most widely used method is a manual algorithm using satellite-based ...

Convective Instability and Boundary Driven Oscillations in a Reaction-Diffusion-Advection Model

, 2017
In a reaction-diffusion-advection system, with a convectively unstable regime, a perturbation creates a wave train that is advected downstream and eventually leaves the system.

Observed relationships between cloud vertical structure and convective aggregation over tropical ocean [PDF]

, 2016
Using the satellite-infrared-based Simple Convective Aggregation Index (SCAI) to determine the degree of aggregation, 5 years of CloudSat-CALIPSO cloud profiles are composited at a spatial scale of 10 degrees to study the relationship between cloud ...
