A limited-area three-dimensional variational data assimilation (3DVAR) system applicable to both synoptic and mesoscale numerical weather prediction is described. The designed for use in time-critical real- time applications freely available the community general research. unique features of this implementation 3DVAR include (a) an analysis space represented by recursive filters truncated eigenmodes background error covariance matrix, (b) inclusion a cyclostrophic term 3DVAR's explicit...
Data assimilation is the process by which observations are combined with short-range NWP model output to produce an analysis of state atmosphere at a specified time. Since its inception in late 1990s, multiagency Weather Research and Forecasting (WRF) effort has had strong data component, dedicating two working groups subject. This article documents history WRF effort, discusses challenges associated balancing academic, research, operational requirements context date. The Model's Community...
Abstract The Weather Research and Forecasting (WRF) model–based variational data assimilation system (WRF-Var) has been extended from three- to four-dimensional (WRF 4D-Var) meet the increasing demand for improving initial model states in multiscale numerical simulations forecasts. goals of this development include operational applications support research community. formulation WRF 4D-Var is described paper. uses as a constraint impose dynamic balance on assimilation. It shown implicitly...
Abstract. We study the compound flooding processes that occurred in Hurricane Florence (2018), which was accompanied by heavy precipitation, using a 3D creek-to-ocean hydrodynamic model. examine important role played barrier islands observed surges coastal watershed. Locally very high resolution is used some watershed areas order to resolve small features turn out be critical for capturing water marks locally. The wave effects are found significant near and have contributed over-toppings...
Abstract In this study, the effect of binary Typhoons Infa and Cempaka on “21.7” heavy rainfall event over Henan Province in China is investigated based numerical simulations. According to rain gauge data, temporal‐spatial distribution precipitation targeted area large‐scale circulation control run show reasonable agreement with observations. By separately excluding relative Typhoon (N_Infa) (N_Cempaka) at initialization, less convergence water vapor flux within obtained, leading a reduction...
Abstract The observation‐minus‐background (O − B) bias characteristics are compared for the Long‐Wave InfraRed (LWIR) channels of Geostationary Interferometric Infrared Sounder (GIIRS) on board Fengyun‐4A (FY‐4A) and Fengyun‐4B (FY‐4B) satellites under clear‐sky all‐sky conditions. Under condition, data quality FY‐4B/GIIRS is better than that FY‐4A/GIIRS. Specifically, standard deviations (<1 K) O B values LWIR smaller those (>1 FY‐4A/GIIRS, especially in carbon dioxide (CO 2 ) ozone 3...
Surface sediment samples from the Kara Sea and adjacent areas were analyzed to investigate diatom distribution patterns in high latitude regions based on species their relationship with temperature. Samples deep Arctic Basin primarily comprised pennatic diatoms centric diatoms, respectively. Rare ice including Fragilariopsis oceanica cylindrus found northern of Sea, close Center Ocean. This region usually has sea packs, which account for a relatively low surface Diatoms near regions, are...
Fish play a crucial role in the estuarine ecosystem due to their ecological and commercial significance. Consequently, it is essential study characteristics of fish communities impacts within estuary. In this study, we employed single-boat bottom trawl conduct four fishery resource surveys April (spring), August (summer), October (autumn), December (winter) 2020 at ten sampling sites along south bank Yangtze River Estuary (SBYRE). The primary objective was assess influence water masses...
Abstract The rapid advancement of data‐driven machine learning (ML) models has improved typhoon track forecasts, but challenges remain, such as underestimating intensity and lacking interpretability. This study introduces an ML‐driven hybrid model, where Pangu forecasts constrain the Weather Research Forecasting (WRF) model using spectral nudging. results indicate that from WRF simulation nudged by significantly outperform those NCEP GFS initial field ECMWF IFS for Typhoon Doksuri (2023)....
Weather systems that interact with one another can enhance coastal water transport, facilitating the movement of waterborne materials. In this study, we examine influence such weather interactions on transport within a tidal pass along coast northern Gulf Mexico, focusing event when Tropical Storm Lee (2011) made landfall and merged an atmospheric cold front, which was leading edge advancing continental polar air mass. We conducted continuous surveys using unmanned surface craft to measure...
FengYun-3E (FY-3E), the fifth satellite in China's second-generation polar-orbiting FY-3 series, was launched on 5 July 2021. FY-3E carries a third-generation microwave temperature sounder (MWTS-3) and humidity Sounder (MWHS-2). In this study, influence of assimilating MWTS-3 MWHS-2 clear-sky radiance data tropical cyclone forecasts regional model is investigated through series assimilation experiments. More than five typhoons from northwest Pacific Ocean during 2024 typhoon season are...
Abstract Atmospheric cold fronts provide recurring forcing for circulations and long-term transport in estuaries with microtides. Multiple horizontal ADCPs were used to obtain time series data from three inlets Barataria Bay. The cover a period of 51 atmospheric between 2013 2015. weather subtidal ocean response are highly correlated the “weather band” (3–7 days). front–associated winds produce alternating flows into, out of, then back into bay, forming an asymmetric “M” low-pass filtered...
Abstract With in situ observations using acoustic Doppler current profilers (ADCPs) and numerical experiments the Finite Volume Coastal Ocean Model (FVCOM), this study investigates atmospheric cold front induced exchange of water between Lake Pontchartrain Estuary coastal ocean through multiple inlets. Results show that subtidal hydrodynamic response is highly correlated with meteorological parameters. Northerly westerly winds tend to push out Pontchartrain, while south east produce currents...
