What Is the Predictability Limit of Midlatitude Weather?
Publisher: American Meteorological Society
Abstract: AbstractUnderstanding the predictability limit of day-to-day weather phenomena such as midlatitude winter storms and summer monsoonal rainstorms is crucial to numerical weather prediction (NWP). This predictability limit ...
Improving Harvey Forecasts with Next-Generation Weather Satellites: Advanced Hurricane Analysis and Prediction with Assimilation of GOES-R All-Sky Radiances
Publisher: American Meteorological Society
Abstract: AbstractHurricane Harvey brought catastrophic destruction and historical flooding to the Gulf Coast region in late August 2017. Guided by numerical weather prediction models, operational forecasters at NOAA provided ...
Simultaneous Assimilation of Planetary Boundary Layer Observations from Radar and All-Sky Satellite Observations to Improve Forecasts of Convection Initiation
Publisher: American Meteorological Society
Dynamics and Predictability of the Intensification of Hurricane Edouard (2014)
Publisher: American Meteorological Society
Abstract: he dynamics and predictability of the intensification of Hurricane Edouard (2014) are explored through a 60-member convection-permitting ensemble initialized with an ensemble Kalman filter that assimilates dropsondes ...
Impact of the Diurnal Radiation Cycle on Secondary Eyewall Formation
Publisher: American Meteorological Society
Abstract: AbstractThe sensitivity of the secondary eyewall formation (SEF) of Hurricane Edouard (2014) to the diurnal solar insolation cycle is examined with convection-permitting simulations. A control run with a real diurnal ...
Impact of Low-Level Jets on the Nocturnal Urban Heat Island Intensity in Oklahoma City
Publisher: American Meteorological Society
Abstract: revious analysis of Oklahoma City (OKC), Oklahoma, temperature data indicated that urban heat islands (UHIs) frequently formed at night and the observed UHI intensity was variable (1°?4°C). The current study focuses on ...
The Roles of an Expanding Wind Field and Inertial Stability in Tropical Cyclone Secondary Eyewall Formation
Publisher: American Meteorological Society
Abstract: he Weather and Research and Forecasting Model (WRF) is used to simulate secondary eyewall formation (SEF) in a tropical cyclone (TC) on the ? plane. The simulated SEF process is accompanied by an outward expansion of kinetic ...
Revisiting the Relationship between Eyewall Contraction and Intensification
Publisher: American Meteorological Society
Abstract: n the widely accepted convective ring model of tropical cyclone intensification, the intensification of the maximum winds and the contraction of the radius of maximum winds (RMW) occur simultaneously. This study shows that ...
A Statistical Investigation of the Sensitivity of Ensemble-Based Kalman Filters to Covariance Filtering
Publisher: American Meteorological Society
Abstract: his paper investigates the effects of spatial filtering on the ensemble-based estimate of the background error covariance matrix in an ensemble-based Kalman filter (EnKF). In particular, a novel kernel smoothing method ...
