Meteodiversity: a new concept to analyse the climate diversity and variation.

Biologists and ecologists have well defined the concept of biodiversity from years, which can quantify from different indexes. Based in a very similar idea, it has been defined the concept of a place’s Meteodiversity in order to be able to calculate trends and to analyse how can global warming be modifying meteorological diversity. Up till now, climate change studies were based in analysing the tendency of some individual variables (mainly rain and temperature). With Meteodiversity the climate change study is more accurate and gives a richer and more integrated information than the several atmospheric variables in climate change.


Professor Jordi Mazón, from Department of Physics and UNESCO Chair on Sustainability-UPC and David Pino, from Department of Physics and Institute of Space Studies of Catalonia (IEEC-UPC),  have published the article in “Meteodiversity: a new concept for quantifying meteorological diversity” in Weather Journal Volume 72. Issue 5.


Inspired by the concept of biodiversity used by biologists and ecologists, the concept of meteodiversity is proposed as a method of characterising the variety of meteorological phenomena in a defined area within a specified period. Similarly to the term biodiversity, meteodiversity takes into account the proportion of individual meteorological phenomena belonging to the main weather that occur in a defined area. The benefits and importance of using this concept are discussed.

For quantification purposes, we propose a meteodiversity index, which, in addition to events and phenomena, should include a large number of atmospheric variables obtained from instrumental and observational records. This index itemises not only events ans phenomena, but also a large number of atmospheric variables obtained from instrumental and observational records.

We use climatic data obtained from the Met Office and European Climate Assessment and Dataset project to evaluate the meteodiversity index, first on a monthly scale for the period 1981–2014 at Llanfairpwllgwyngyll (UK), and then on an annual scale for 1962–2014 at Barcelona (Spain) and Helsinki (Finland). The weather diversity and the trends over these cities have been analyzed.
