Development and dissemination of seasonal forecasts are integral components of the climate services provided by numerous meteorological services worldwide, offering estimates of meteorological variables on a seasonal time scale to aid local warning systems and decision‐making processes. The World Meteorological Organization (WMO) recommends that op...

Saharan warm intrusions are air masses that develop over the Saharan region and that get advected into surrounding regions, creating anomalous atmospheric situations in other regions. This paper focuses on the characteristics of these intrusions into the Western Mediterranean region (WMed) and their relationship with extreme temperatures in the nei...

The performance of a set of 26 CMIP6 global climate models (GCMs) in the Euro-Mediterranean region is analyzed based on a classification of atmospheric circulation patterns (CPs). Their spatial and temporal variability representation, including the associated surface conditions in ERA5 during 1950-2014, allows a ranking of the best-performing GCMs....

The observed warming in the Western Mediterranean (WMed) region over recent decades is projected to continue, outpacing the global average, making the region a prominent climate change hotspot. Even within this relatively small area, the combination of natural climate variability and anthropogenic climate change creates significant spatial variatio...

This study presents a framework to assess climate variability and change through atmospheric circulation patterns (CPs) and their link with regional processes across time scales. We evaluate the CPs impacts on daily rainfall, and maximum and minimum temperatures in the Iberian Peninsula using sea-level pressure (SLP) during 1950–2022. Different sen...

Climate extreme indices —-encompassing absolute values, percentile-based, and spell indices—- are analyzed over Spain during 1951-2020 using daily precipitation (PR), maximum and minimum temperatures (TX and TN) from the AEMET high-resolution dataset. The indices focus on the frequency, intensity, and duration of extremes. A general warming trend i...

We provide a dataset of tornadoes and waterspouts in Chile from 1554 to present based in chronicles, newspaper articles, social media, scientific literature and books. The database includes only those events that have been qualified as more than likely a tornado or waterspout based on a subjective qualification by the researchers. For each tornado...

We characterize trends in maximum seasonal daily precipitation (seasonal Rx1day), minimum (Tn), and maximum (Tx) daily temperatures during days with precipitation over continental Chile for the period 1979–2017, using surface stations and the AgERA5 gridded product derived from the ERA5 reanalysis dataset. We also examine seasonal trends of Sea Sur...

The Antarctic Peninsula (AP) experienced a new extreme warm event and record-high surface melt in February 2022, rivaling the recent temperature records from 2015 and 2020, and contributing to the alarming series of extreme warm events over this region showing stronger warming compared to the rest of Antarctica. Here, the drivers and impacts of the...

Plain Language Summary Changes in the amount of rain Central Chile gets from year to year is often related to how the atmosphere behaves over the Southern Pacific Ocean. Specifically, it is connected to the interaction between storm tracks and certain wind patterns that respond to changes in the amount of rainfall in tropical areas. Our research sh...

We characterize trends in maximum seasonal daily precipitation (seasonal Rx1day), and minimum (Tn), and maximum (Tx) daily temperatures during days with precipitation over continental Chile for the period 1970-2017, using surface stations and the AgERA5 gridded product derived from the ERA5 reanalysis dataset. We also examine seasonal trends of Sea...

Interannual variability of precipitation in Central Chile has long been associated with changes in the Southern Pacific dry atmospheric dynamics, due to the interaction of the extratropical storm track with the polar anticyclonic circulations established by the Pacific South American (PSA) teleconnection mode, which results from changes in tropical...

The Antarctic Peninsula (AP) experienced a new extreme warm event and record high surface melt in February 2022, rivaling the recent temperature records from 2015 and 2020, and contributing to an alarming series of extreme warm events there. The northern/northwestern AP was directly impacted by an intense atmospheric river (AR) bringing anomalous h...

La Dirección Meteorológica de Chile (DMC), emite todos los meses un pronóstico estacional y subestacional (S2S) de precipitación, basado en un pronóstico de consenso utilizando modelos dinámicos y estadísticos. El presente trabajo busca realizar una evaluación del desempeño de los pronósticos estacionales con tal de analizar posibles mejoras al sis...

Since the end of 2019, the Climate Services Office of the Chilean Weather Service (DMC) began a renewal of the seasonal and sub-seasonal forecast system (S2S) for precipitation and temperatures, going from a seasonal forecast based purely on the sea surface temperature (SST) in the El Niño 3.4 region to an ensemble forecast based on members contain...

A major storm impacted the subtropical Andes during 28–31 January 2021 producing 4-days accumulated precipitation up to 100 mm over central-south Chile. These are high accumulations even for winter events but the storm occurred in the middle of the summer when precipitation in virtually absent, conferring it an extraordinary character. Similar stor...

In late May 2019, at least seven tornadoes were reported within a 24-h period in southern Chile (western South America, 36°–38°S), including EF1 and EF2 events causing substantial damage to infrastructure, dozens of injuries, and one fatality. Despite anecdotal evidence and chronicles of similar historical events, the threat from tornadoes in Chile...

Faced with the greatest public health crisis of our time, people must work together and learn from each other to overcome the complex challenges facing our communities, countries, and the world. Climate-related hazards are one of those challenges; they exacerbate already challenging public health conditions and impact not just people, but also the...

Regional Climates is one chapter from the State of the Climate in 2019 annual report. Compiled by NOAA’s National Centers for Environmental Information, State of the Climate in 2019 is based on contributions from scientists from around the world. It provides a detailed update on global climate indicators, notable weather events, and other data coll...

Durante las jornadas del 30 y 31 de mayo de 2019, se registraron al menos dos violentos tornados en la Región del Biobío, afectando a la ciudad de Los Ángeles y Talcahuano/Concepción, produciendo daños materiales, heridos y el lamentable fallecimiento de una persona. Las primeras estimaciones de daños realizadas por los organismos oficiales, ademá...

The role played by tropical teleconnections in the precipitation of Central Chile through Rossby waves propagating over the Pacific basin has been long recognized in studies since the early 1980s. The main source of internannual variability is connected to ENSO through the teleconnections along the Pacific South American sector. The vision we have...

El papel que desempeñan las teleconexiones tropicales en la precipitación de Chile Central ha sido reconocido en estudios desde principios de los 1980s. La visión que se tiene de esta teleconexión involucra, la existencia de un bloqueo, en latitudes altas, y una difluencia que desviaría el flujo de latitudes medias hacia latitudes más bajas durante...

Enero de 2017 se caracterizó por presentar un patrón sinoptico de bloqueo atmosférico sobre Chile, provocando un aumento de temperaturas generalizado a lo largo del país, récords de temperatura máxima y una gran cantidad de días extremadamente cálido.

From 18 to 27 March 2015, northern, central, and southern Chile experienced a series of extreme hydrometeorological events. First, the highest surface air temperature ever recorded in Santiago (with reliable records dating to 1877), 36.8°C at Quinta Normal, was measured at 15:47 local time on 20 March 2015. Immediately following this high heat even...

La principal causa de tormentas eléctricas y aluviones en la cordillera central de Chile son las Bajas Segregadas (BSs), que en su paso por una zona determinada pueden dejar gran cantidad de precipitación en cortos periodos de tiempo, produciendo aumento en caudales, pudiendo ocasionar inundaciones. Hay evidencias de que a partir de 1990 ha aumenta...

During the second half of March 2015, a sequence of atmospheric anomalies caused both record temperatures and precipitation in Chile.
