A Multi-Platform In Situ Kinematic and Microphysical Analysis of a Hybrid Parallel–Trailing Stratiform Mesoscale Convective System
(2022)Parallel stratiform–type mesoscale convective systems (MCS) have been found to comprise less than 20% of the central U.S. MCSs, but parallel stratiform MCSs have been reviewed by few studies and only a handful have been ... -
Use of a Reflectivity Operator Based on Double-Moment Thompson Microphysics for Direct Assimilation of Radar Reflectivity in GSI-Based Hybrid En3DVar
(2022)The assimilation of reflectivity (Z) within 3DVar or hybrid ensemble-3DVar (En3DVar) requires the adjoint of the Z observation operator. With the 3DVar or En3DVar method, previous studies often use Z operators consistent ... -
Assessing the Sensitivity of the Tropical Cyclone Boundary Layer to the Parameterization of Momentum Flux in the Community Earth System Model
(2022)Recent studies have demonstrated that high-resolution (∼25 km) Earth System Models (ESMs) have the potential to skillfully predict tropical cyclone (TC) occurrence and intensity. However, biases in ESM TCs still exist, ... -
The Effect of a Kona Low on the Eastern Pacific Valentine’s Day (2019) Atmospheric River
(2022)A high-impact atmospheric river (AR) event that made landfall on the U.S. West Coast on Valentine’s Day of 2019 and produced widespread flooding in California is examined. The U.S. Naval Research Laboratory cloud resolving ... -
Supercell Thunderstorm Charge Structure Variability and Influences on Spatial Lightning Flash Relationships with the Updraft
(2022)Relationships between lightning flashes and thunderstorm kinematics and microphysics are important for applications such as nowcasting of convective intensity. These relationships are influenced by cloud electrification ... -
Use of Power Transform Total Number Concentration as Control Variable for Direct Assimilation of Radar Reflectivity in GSI En3DVar and Tests with Six Convective Storms Cases
(2022)When using a double-moment microphysics scheme, both hydrometeor mixing ratios and number concentrations are part of the state variables that are needed to initialize convective-scale forecasting. In the Thompson microphysics ... -
Tropical Cyclone Data Assimilation with Coyote Uncrewed Aircraft System Observations, Very Frequent Cycling, and a New Online Quality Control Technique
(2022)A unique dataset obtained from the Coyote small uncrewed aircraft system (sUAS) in the inner-core boundary layer of Hurricane Maria (2017) is assimilated using NOAA’s Hurricane Ensemble Data Assimilation System (HEDAS) for ... -
Model Uncertainty Representation in a Convection-Permitting Ensemble—SPP and SPPT in HarmonEPS
(2022)The stochastically perturbed parameterizations scheme (SPP) is here implemented and tested in HarmonEPS—the convection-permitting limited area ensemble prediction system by the international research program High Resolution ... -
The Anatomy of a Series of Cloud Bursts that Eclipsed the U.S. Rainfall Record
(2022)A series of extreme cloudbursts occurred on 14 April 2018 over the northern slopes of the island of Kaua‘i, Hawaii. The storm inundated some areas with 1262 mm (∼50 in.) of rainfall in a 24-h period, eclipsing the previous ... -
Preliminary Assessment of MetOp-Based Temperature and Humidity Statistical Retrievals within the 3D-Var AROME-France Prediction System
(2022)The main objective of the study is to evaluate the feasibility and benefits of assimilating satellite temperature and humidity soundings (aka Level 2 or L2 profiles), instead of radiances, from the EUMETSAT Advanced ... -
The Multigrid Beta Function Approach for Modeling of Background Error Covariance in the Real-Time Mesoscale Analysis (RTMA)
(2022)We describe a method for the efficient generation of the covariance operators of a variational data assimilation scheme, which is suited to implementation on a massively parallel computer. The elementary components of this ... -
Why Does Convection Weaken over Sumatra Island in an Active Phase of the MJO?
(2022)This study investigated the diurnal cycle of convection over Sumatra Island in an active phase of the Madden–Julian oscillation (MJO) during the Pre-Years of the Maritime Continent (YMC) observation campaign in December ... -
