Abstract. Cut-off lows (COLs) are mid-tropospheric cyclonic systems that frequently form over southern South America, where they can cause high-impact precipitation events. However, their prediction remains a challenging task, even in state-of-the-art numerical weather systems. In this study, we assess the skill of Global Ensemble Forecast System (GEFS) predicting COL formation and evolution American region highest frequency intensity such events observed. The target season is austral autumn...
Abstract An aircraft turbulence encounter over the Drake Passage is investigated by combining unique high‐frequency flight level data, vertical profiles of a near‐simultaneous radiosonde profile and numerical results from global regional weather prediction (NWP) models. Meteorological analysis reveals an intense polar low propagating Bellinghausen Sea toward Passage. A small deep stratospheric intrusion formed tropopause fold that promoted strong upper‐level frontogenesis enhanced shear...
Abstract We study a strong clear air turbulence (CAT) event experienced by the German High‐Altitude Long‐Range research aircraft (HALO) during Southern Hemisphere Transport, Dynamics, and Chemistry campaign. HALO encountered CAT leeward of southern Andes Mountains, where tropospheric airflow favored vertically propagating mountain waves that were refracted southeastward into core tropopause jet. Turbulence is quantified using spectral quantities structure functions computed from in situ 100...
The dynamic and thermodynamic processes involved in the life cycle of a cutoff low occurred March 2007 are studied. These analyzed using vorticity equations set analyses generated with BRAMS model. main that explain segregation subtropical part trough horizontal advection cyclonic at high levels warm middle levels, both over Pacific Ocean extending south to Patagonia region, building ridge located upstream trough. Increased intensity upper level pressure system is mainly explained by...
En este trabajo se analiza el ciclo de vida una baja segregada que afectó sur Sudamérica entre 26 Marzo y 2 Abril del 2007 explora la relación existente las diferentes etapas sistema precipitación ocurrida sobre franja central Argentina. Además evalúa si otros procesos coadyuvaron para ocurrencia misma. Las características más relevantes son su larga duración lento desplazamiento, ya inicio fin desplaza sólo 780 km, manteniéndose estacionario, durante segregación madurez, por 56 hs frente a...
Abstract Predicting radiative forcing due to Antarctic stratospheric ozone recovery requires detecting changes in the vertical distribution. In this endeavor, Limb Profiler of Ozone Mapping and Suite (OMPS-LP), aboard Suomi NPP satellite, has played a key role providing profiles over Antarctica since 2011. Here, we compare derived from OMPS-LP data (version 2.5 algorithm) with balloon-borne ozonesondes launched 8 stations period 2012–2020. Comparisons focus on layer 12.5 27.5 km include...
