    Descripció del contingut i pla d'activitats:
    Rapid and sudden advections of very warm and cold phenomena, which are
    proposed to call as flash heat and flash cool, will be investigated in this PFG, along
    the XX century in the Iberian peninsula and Europe. By using daily temperature
    series, an algorithm will be proposed useful for detecting and the analysis of these
    type of events, in order to find the trend since 1900 as well as to determine the
    possible risk over the aeronautics.
     
    Overview (resum en anglès):
    Hot and cold waves are perfectly defined by different meteorology agencies in matters of time and area. However, there is a phenomenon that takes place on a lower spatial and temporal scale. It is known as Flash Heat and Flash cold.

    According to the Spanish State Meteorology Agency (AEMet), a heat wave is an episode of, at least, three consecutive days where 10% or more of its stations record maximum temperatures that are over 95% of their list of maximum daily temperatures in the months of July and August for the period between 1971 and 2000.

    Likewise, AEMet considers that a cold wave is an episode of, at least, three consecutive days where 10% of its stations register minimum temperatures below 5% of their recorded minimum daily temperatures of January and February from 1971 until 2000.

    Following the research done by Mazón et al. (2014), where the Flash Heat phenomenon is described, we have developed its investigation and defined the Flash Cold by analogy.

    The main purpose of this paper is to analyze the data presented in order to explain the phenomena that we have studied. To develop our research, daily data from 22 different weather stations across Spain dating from 1900 until 2010 have been used as well as data collected from NETCDF for the period between 1970 and 2010. Working with these two formats has allowed us to detect discrepancies between using real and estimated values.

    Once all the data has been analyzed, the effect that these phenomena have in aeronautics will be studied through a theoretical analysis of the equations and the relation between its terms.

    Lastly, we will present the conclusions obtained through our research in order to finish this study and complete the project.
