About this Research Topic
Classifications of circulation weather systems have a long history in meteorology and climatology. Starting with manual classifications over specific regions of the globe, these tools (generally called “catalogs of synoptic types”) were restricted mainly to weather forecasting and historical climate variability studies. In the last decades, the advance of computing resources and the availability of datasets have fostered the development of fast and objective methods that process large amount of data.
In recent years numerous methods of circulation type classification have been designed, showing their usefulness on a wide range of applications in scientific domains related to weather, climate, and environment.
In this Research Topic we welcome contribution of original research articles, review articles, and methodological advances in circulation weather types. The highlight of this Research Topic includes, but is not limited to, studies aiming to:
1. The development of new circulation weather types’ classifications and inter-comparisons between different methodologies, including the use of different atmospheric reanalysis datasets.
2. Circulation weather types’ applications to climate and environment. They include analyses of the relationship between circulation weather types and climate variables (e.g., temperature, precipitation, wind speed, snow, lightning activity, tropopause height, stratospheric ozone, etc.), and the reconstruction of environmental-related series (e.g., air quality, agro and forest meteorology, biometeorology, hydrology, renewable energy, oceanography, etc) from a circulation weather-typing approach.
3. The exploration of past climate variability by using either early instrumental data to reconstruct regional climatic variables or climatic proxies as a mean to infer atmospheric variability during the last centuries.
4. The quantification of the relative contribution of frequency changes and internal (the so-called within) changes in weather types as a way to explain specific anomalous periods or events.
5. The use of circulation weather types to analyse and diagnose (from an individual or a climatological-based perspective)extreme episodes such as droughts, heat and cold waves, river floods, flash floods, landslides, forest fires or storm surges.
6. The assessment of linkages between atmospheric modes of low-frequency variability and regional circulation weather type patterns as well as a better understanding of bi-directional changes (i.e. how changes in intensity or shifts in position of the modes of low-frequency variability influence changes in local circulation, and how changes in circulation weather types can shape the spatial patterns and temporal variability of the large-scale modes of atmospheric variability).
7. Circulation Weather types as seamless tools to validate seasonal forecasts and climate model simulations addressing predictability studies and future changes in regional weather types under different climate scenarios.
