A nature run is a critical component of an observing system simulation experiment (OSSE), which framework for evaluating the potential impact additional observations, enhanced systems, or alternative data assimilation schemes toward improving numerical weather forecasts. The period simulated generated by research‐quality model, from synthetic observations are sampled and provided to forecast model. This paper describes development validation that depicts life cycle strong hurricane over...
Observations of tropical cyclones (TC) from aircraft and in situ platforms provide critical unique information for analyzing forecasting TC intensity, structure, track, their associated hazards. This report, prepared the tenth International Workshop on Tropical Cyclones (IWTC-10), discusses data collected around world TCs over past four years since IWTC-9, improvements to observing techniques, new instruments designed achieve sustained targeted atmospheric oceanic observations, select...
Abstract The potential impact of Doppler wind lidar (DWL) observations from a proposed optical autocovariance (OAWL) instrument is quantified in observing system simulation experiments (OSSEs). OAWL design would provide profiles useful vectors along ground track to the left International Space Station (ISS), which 51.6° inclination low-Earth orbit (LEO). These are simulated realistically, accounting for cloud and aerosol distributions inferred OSSE nature runs (NRs), measurement sampling...
This study presents wind observations from an airborne Doppler Wind Lidar (ADWL) in 2016 tropical cyclones (TC). A description of ADWL measurement collection and quality control methods is introduced for the use a TC environment. Validation against different instrumentation on-board National Oceanographic Atmospheric Administration’s WP-3D aircraft shows good agreement retrieved measured speed direction. Measurements taken instruments such as global positioning system dropsonde, flight-level...
Abstract Observing System Simulation Experiments (OSSEs) are an important tool for evaluating the potential impact of new or proposed observing systems, as well trade-offs in system design, and developing assessing improved methodology assimilating observations. Extensive OSSEs have been conducted at National Aeronautical Space Administration (NASA) Goddard Flight Center (GSFC) Oceanic Atmospheric (NOAA) Atlantic Oceanographic Meteorological Laboratory (AOML) over last three decades. These...
This study presents a verification and an analysis of wind profile data collected during Tropical Storm Erika (2015) by Doppler Wind Lidar (DWL) instrument aboard P3 Hurricane Hunter aircraft the National Oceanic Atmospheric Administration (NOAA). DWL-measured winds are compared to those from nearly collocated GPS dropsondes, show good agreement in terms both magnitude asymmetric distribution field. A comparison speeds versus dropsonde-measured yields reasonably correlation (r2 = 0.95), with...
Abstract Since 2005, NOAA has conducted the annual Intensity Forecasting Experiment (IFEX), led by scientists from Hurricane Research Division at NOAA’s Atlantic Oceanographic and Meteorological Laboratory. They partner with Aircraft Operations Center, who maintain operate WP-3D Gulfstream IV-SP (G-IV) Hunter aircraft, NCEP’s National Center Environmental Modeling task airborne missions to gather data used forecasters for analysis forecasting ingest into operational numerical weather...
Abstract Observation system experiments (OSEs) are conducted to assess the potential impacts of horizontal line‐of‐sight wind profile observations from Aeolus satellite on tropical cyclone (TC) forecasting. The OSEs utilize operational Hurricane Weather and Research Forecasting (HWRF) model. include 226 forecasts seven TC cases in Atlantic Eastern Pacific basins. Comparisons between model background winds show that consistently stronger than those HWRF. Data assimilation statistics also...
Abstract The impact of assimilating ocean surface wind observations from the Cyclone Global Navigation Satellite System (CYGNSS) is examined in a high-resolution Observing Simulation Experiment (OSSE) framework for tropical cyclones (TCs). CYGNSS planned National Aeronautics and Space Administration constellation microsatellites that utilizes existing GNSS satellites to retrieve speed. In OSSE, speed data are simulated using output “nature run” as truth. case study regional Hurricane Weather...
Abstract Aircraft reconnaissance missions remain the primary means of collecting direct measurements marine atmospheric conditions affecting tropical cyclone formation and evolution. The National Hurricane Center tasks NOAA G-IV aircraft to sample environmental that may impact development a threatening make landfall in United States or its territories. These data are assimilated into deterministic models used produce real-time analyses forecasts for given cyclone. Existing targeting...
Abstract This study examines how varying wind profile coverages in the tropical cyclone (TC) core, near-environment and broader synoptic environment affect structure evolution of a simulated Atlantic hurricane through data assimilation. Three sets observing system simulation experiments (OSSEs) are examined this paper. The first experiment establishes benchmark for case specific to forecast used by assimilating idealized profiles throughout parent domain. second presents TC analyses...
One of the most important applications a space-based Doppler Wind Lidar (DWL) would be to improve atmospheric analyses and weather forecasting. Since mid-1980s, Observing System Simulation Experiments (OSSEs) have been conducted evaluate potential impact DWL data on numerical prediction (NWP). All these OSSEs shown significant beneficial global forecasts. In more recent years, limited number experiments hurricane forecasting also begin real airborne observations. These latest studies suggest...
