Abstract. The development phase (DP) of the EUMETSAT Satellite Application Facility for Support to Operational Hydrology and Water Management (H-SAF) led design implementation several precipitation products, after 5 yr (2005–2010) activity. Presently, five estimation algorithms based on data from passive microwave infrared sensors, board geostationary sun-synchronous platforms, function in operational mode at H-SAF hosting institute provide near real-time products different spatial temporal...
Abstract Previous works suggest that more El Niño–like conditions can be expected over the South American (SA) climate and atmospheric circulation because of similarity predominately warm in sea surface temperature (SST) central-equatorial Pacific after 1976/77 summer with those SSTs during Niño events. Here, (October to March) low-level southern SA is studied order determine specific changes related global transition 1976/77. The rotated principal component analysis applied daily 850-hPa...
ABSTRACT This work shows statistical evidence for lunar nodal cycle influence on the low‐frequency summer rainfall variability over plains to east of subtropical Andes, in South America, through long‐term sea surface temperature ( SST ) variations induced by amplitude diurnal tides southwestern Atlantic SWSA ). In years strong (weak) tides, tide‐induced diapycnal mixing makes cooler (warmer) together with low (high) air pressures surroundings Malvinas/Falklands Islands , possibly mean...
The interannual-to-multidecadal variability of central-west Argentina (CWA) summer (October–March) precipitation and associated tropospheric circulation are studied in the period 1900–2010. Precipitation shows significant quasi cycles with periods about 2, 4–5, 6–8, 16–22 yr. quasi-bidecadal oscillation is from early 1910s until mid-1970s present pressure time series over southwestern South Atlantic. According to lower-frequency spectral variation, a prolonged wet spell observed 1973 2000s....

ABSTRACT This work focuses on the analysis of spatial and temporal variability precipitation in central region southern Central Argentina ( SCA ), a climate transition area which has experienced an important agricultural expansion. For this purpose, gauge station datasets available were extensively used. The annual cycle shows defined dry season (May–August) wet (September–April). Wet represents over 85% totals. A regionalization wet‐season suggests five subregions with spatially homogeneous...
Abstract Mendoza Province is the major Argentinian vitivinicultural region, and its grape production fundamental for national vintage. The 1979–2009 climate–annual yield relationships are analyzed, total shown to depend significantly on regional “summer” (October–March) precipitation. Precipitation negatively affects yields through plant disease damage/destruction by hail. At interannual scales, summer precipitation variability can explains 25% of variance. Summer modulates with a 6–8-yr...
Abstract The seasonal influence of the phases El Niño‐Southern Oscillation (ENSO) and Southern Annular Mode (SAM) on precipitation over eastern Patagonia is examined. Also, their impact in generating persistent daily easterly moisture flux leading to events. significant signatures drivers are found March–April–May (MAM), June–July–August (JJA) for ENSO November–December–January (NDJ) SAM. Over east coast, mainly favoured owing an overall growth mean number days (~30%) by central Niño JJA...
Abstract Precipitation anomalies over subtropical Argentina in eastern South America (ESSA) show significant signatures of the El Niño Southern Oscillation (ENSO) during SONDJ (from September to January) season. The correlation maps between seasonal precipitation and C‐index a dipole structure with positive ESSA negative American convergence zone. Based on principal component analysis, within season ENSO events were discriminated into three categories typical, atypical nontypical, regarding...
Abstract The relationship between daily precipitation and unusually persistent easterly wind recorded at station level along the coast of Eastern Patagonia is examined. Easterly events that persist for more than 20 h (E) are infrequent in Comodoro Rivadavia (CMR); but about 80% times they do occur exceeds 1 mm. Although 2‐day easterlies (2E) only 1% time CMR associated with 20% >75% percentile rain events. occurrence days (P ≥ mm) during 2E (P1&2E) far from randomness most stations....
El Ni˜no-Southern Oscillation (ENSO) is the major forcing of interannual precipitation variability over South America (SA), especially from September to December, through a convection dipole Atlantic Convergence Zone (SACZ) region and southeastern SA (SESA). However, mechanisms for midsummer (January) under ENSO events less known. A cluster analysis applied January OLR anomalies Tropical-Subtropical depicts two clusters linked signs between SACZ SESA. Most La Ni˜na (LN) (10 out 13 events)...
Abstract The relationship between the October (spring) total ozone column (TOC) midlatitude zonal asymmetry over Southern Hemisphere (SH) and stratospheric quasi-stationary wave 1 (QSW1) interannual phase variability is analyzed. Once contributions to TOC from known global predictors, estimated with a multiregression model, are removed, residual observed be dynamically coupled QSW1 behavior. variability, when classified according specifically designed indices, yields different circulation...
Total ozone relationships with selected upper troposphere/lower stratosphere variables (400‐ and 70‐hPa temperatures, tropopause height temperature, geopotential height, 340‐K potential vorticity), as well between the variables, are analyzed on decadal scales over Southern Hemisphere midlatitudes for period 1980–2000.
