The Canary Islands are characterized by having a mild and dry climate
throughout the year, however, rainfall is more abundant than expected due to the relief
of the islands. Furthermore, under specific meteorological circumstances, the
orography of the islands produces an amplifying effect, causing severe local
precipitation events. The importance of predicting these events is key for aeronautical
navigation, agriculture, sports and, especially, the prevention of natural disasters.
Specifically, this work will study the heavy rains that took place in Santa Cruz de
Tenerife in 2002 and caused floods throughout the capital, losses worth millions of
euros and the death of eight people. Furthermore, the AEMET was not able to predict
the magnitude of these precipitations, so the population was not alerted.
Likewise, the AEMET carried out a subsequent study in which they tried to
reproduce these precipitations by analyzing in depth the wind and pressure fields and
the convective structures. In addition, they carried out some simulations modifying the
resolution to try to improve the results. However, due to the complexity of the
phenomenon and the scarcity of data, they did not succeed.
In this work, the same day will be analyzed with the WRF model to try to
replicate these atmospheric conditions. For this, several simulations will be carried out
using different parameters to determine which set of them provides results closest to
the event that occurred on the island of Tenerife.
