Abstract The association between Southern Hemisphere cyclones and anticyclones the El Niño–Southern Oscillation (ENSO), southern annular mode (SAM), Antarctic sea ice extent (SIE), rainfall in Perth Melbourne is explored. Those cities are, respectively, located southwestern southeastern corners of Australia, where substantial decreasing trends have been observed over last decades. need for a more unified understanding large-scale anomalies storm indicators associated with climate features...
Abstract Satellite altimetry provides an immensely valuable source of operational significant wave height (Hs) data. Currently, altimeters on board Jason-1 and Envisat provide global Hs observations, available within 3–5 h real time. In this work, data from these are validated against in situ buoy the National Data Buoy Center (NDBC) Marine Environmental Service (MEDS) networks. cover a period three years for more than four Jason-1. Collocation criteria 50 km 30 min yield 3452 2157...
The generation and evolution of ocean waves by wind is one the most complex phenomena in geophysics, great practical significance. Predictive capabilities respective wave models, however, are impaired lack field situ observations, particularly extreme Metocean conditions. paper outlines highlights important gaps understanding processes suggests a major observational program Southern Ocean. This large, but poorly investigated part World Ocean home to weather around year. network would include...
Abstract Wind‐wave hindcast data have many applications including climatology assessments for renewable energy projects, maritime engineering design, event‐based impact assessments, generating boundary conditions further downscaling, amongst others. Here, we present a global wave with nested high‐resolution grids the Exclusive Economic Zones of Australia and south west Pacific Island Countries, that is extended in time monthly. The model employs strategic methods to incorporate effects...
Abstract Global wave hindcasts are developed using the third generation spectral model WAVEWATCH III with observation‐based source terms (ST6) and a hybrid rectilinear‐curvilinear, irregular‐regular‐irregular grid system (approximately at ). Three distinct global produced: (a) long‐term hindcast (1979–2019) forced by ERA5 conventional winds (b) two short‐term (2011–2019) driven NCEP climate forecast (CFS)v2 neutral , respectively. The input field for ice is sourced from Ocean Sea Ice...
Abstract Offshore reef systems consist of individual reefs, with spaces in between, which together constitute the matrix. This is first comprehensive, large-scale study, influence an offshore system on wave climate and transmission. The focus was Great Barrier Reef (GBR), Australia, utilizing a 16-yr record height from seven satellite altimeters. Within GBR matrix, not strongly dependent matrix submergence. suggests that after initial breaking at seaward edge energy penetrates has little...
Abstract In this study, we present simulations of a burned area at European scale for the period 1990–2009 conducted with Community Land Model (CLM). By using statistics on fire counts and mean suppression time from Fire Database, refined parameterization functions describing human ignition/suppression, modified description biomass availability fires. The results obtained model show an improvement spatial interannual variability area: bias is reduced by 45%, explained variance increased...
Abstract The use of numerical guidance has become integral to the process modern weather forecasting. Using various techniques, postprocessing model output been shown mitigate some deficiencies these models, producing more accurate forecasts. operational consensus forecast scheme uses past performance bias-correct and combine forecasts produce an improved at locations where recent observations are available. This technique was applied significant wave height (Hs), peak period (Tp), 10-m wind...
Abstract This study examines the application of three different variations linear-regression corrections to surface marine winds from Australian Bureau Meteorology’s recently implemented operational atmospheric model. A simple correction over entire domain is found inadequately account for geographical variation in wind bias. addressed by considering that vary space. Further, these spatially varying are extended time. In an environment, error characteristics forcing can be expected change...
Abstract The New Zealand Defence Force (NZDF) has established a permanent wave observation station near Campbell Island, south of (52 45.71 S, 169 02.54E). site was chosen for logistical convenience and its unique location adjacent to the highly energetic Southern Ocean; allowing instrumentation typically deployed on continental shelf be used in this rarely observed southern environment. From February 2017, Triaxys Directional Wave Buoy moored 147 m depth, some 17 km island, with satellite...
