Descripció del contingut i pla d'activitats:
Weather is a dynamic system. It shows a variability of phenomena and events. The diversity in weather can be defined by using the term of Meteodiversiy, a concept than describe and quantifies the diversity of weather over a region. It can be seen as a measurement about the entropy of weather by using the Meteordiversity index (MI) defined by Mazon et al. (2017).
One step more in the investigation about meteodiversity is to adapt and to apply this index to quantify the diversity of the extreme and severe weather, through the definition of a new index, the Extreme Meteorological Index (EMI). The aim of the project is to quantify the diversity of extreme weather over several locations, to find trends and quantify the extreme weather variability. Data and the definitions of extreme weather from the World Meteorological Organization will be selected, in order to calculate the EMI, as well as to analyze trends during last years. The investigation and calculations of EMI will be focused over several locations where could have any influence over the aeronavigation.

 
Overview (resum en anglès):
The concept of meteodiversity is used to determine and characterize the variety of meteorological phenomena in a region during a given period. Specifically, using the Meteodiversity Index (MI), we can quantify the climatic variability based on a set of variables which measures the occurrence of a series of meteorological phenomena.

The present work aims to obtain the geographical distribution of MI along Spain (without Canary Islands, Ceuta and Melilla) throughout the period 1981-2010 and considering two different types of variables: average variables and extreme variables. The extreme variables endow our analysis with greater precision and rigor by evaluating phenomena that are distant from the average values.

The results take into account the characteristic climatic situations on a synoptic scale for each seasonal period, the specific distributions of each variable considered in meteodiversity computation and the Köppen climate classification. The geographical distribution of MI will be used to characterize the aeronautical sector most conflictive areas, throughout the study territory, in terms of meteorological diversity.

Furthermore, in A Coruña, Adolfo Suarez Madrid-Barajas, Bilbao and Josep Tarradellas Barcelona-El Prat airports, the influence of MI variables is studied in order to see if they adjusts with the climatic situations exposed in the aerodrome meteorological guides, arranged by AEMET only for these airports.

All the previous topics are collected throughout the project and analysed obtaining the pertinent considerations regarding our study, its limitations and future work inside the field of meteorological diversity.
