Κλιματική ανάλυση της θερμοκρασίας της θάλασσας φια την χειμερινή περίοδο = Climate nalysis of the sea temperature for the winter season.
Περίληψη
Το δεύτερο κεφάλαιο αποτελεί την ανάλυση των αποτελεσμάτων, η οποία επιτυγχάνεται με την χρήση χαρτών θερμοκρασίας (γραφήματα) οι οποίοι δημιουργήθηκαν από την βάση δεδομένων: https://psl.noaa.gov/cgi-bin/data/getpage.pl, εφαρμόζοντας συγκεκριμένες παραμέτρους για κάθε πενταετία από το 1960 έως το 2020 για τους μήνες Νοέμβριο, Ιανουάριο και Μάρτιο (χειμερινή περίοδος). Σε αυτό το κεφάλαιο αναλύονται όλες οι μέσες θερμοκρασίες και οι ανωμαλίες τους σε παγκόσμια έκταση, και επισημαίνονται οι ακραίες τιμές θερμοκρασίας της επιφάνειας της θάλασσας για διαφορετικά γεωγραφικά μήκη και πλάτη. Επιπλέον στην αρχή κάθε πενταετίας και μήνα δίνεται μια συνολική εικόνα των ακραίων τιμών της θερμοκρασίας της θάλασσας σε όλη την έκταση του χάρτη.
Το τρίτο κεφάλαιο αποτελεί το δεύτερο μέρος της ανάλυσης, αυτή τη φορά όμως με την χρήση Hovmollers (χρονοδιαγραμμάτων). Τα συγκεκριμένα γραφήματα χρησιμοποιούνται για την ανάλυση των θερμοκρασιακών ανωμαλιών της επιφάνειας της θάλασσας σε ετήσια βάση και για συγκεκριμένο γεωγραφικό μήκος και πλάτος. Η ανάλυση με Hovmollers, έγινε ανά εικοσαετία για την ίδια χρονική περίοδο (1960-2020) και περιγράφει την ετήσια θερμοκρασία της θάλασσας του Ειρηνικού Ωκεανού (180° γ.μ.) και του Ατλαντικού ωκεανού (30°Δ γ.μ.) για την χειμερινή περίοδο.
Τέλος, στο τέταρτο και τελευταίο κεφάλαιο παρουσιάζονται τα συμπεράσματα της ανάλυσης των αποτελεσμάτων και γίνεται μια συζήτηση για τις ακραίες τιμές των ανωμαλιών θερμοκρασίας.
In this thesis, the sea surface temperature of the global sea, for the winter season and for a 60-year period (1960 - 2020), is analyzed. The first chapter is an introduction, where important definitions and meanings are explained, which are necessary for the easier and better understanding of the thesis. Moreover, information is given about the characteristics of different sea surface temperature estimation methods and results regarding the measurements, in graphic form.
The second chapter is the analysis of the results, which is achieved with the use of temperature maps (graphics) which were plotted from the data basis: https://psl.noaa.gov/cgibin/data/getpage.pl implementing certain parameters for every five years, from 1960 to 2020, for the months November, January and March (winter season). In this chapter are being analyzed all the mean temperatures and their anomalies in a global extent and are being pointed out all the extreme values of the sea surface temperature for different longitudes and latitudes. Furthermore, at the beginning of every five-year period and month a general assessment for all the extreme values of the sea temperature is given for the whole extent of the map.
The third chapter is the second phase of the analysis, however this time with the use of Hovmollers (time-section plots). These graphs are being used for the analysis of the sea surface temperature in an annual basis and for specific longitude and latitude. The Hovmollers were analyzed for every 20-year period for the same time period (1960-2020), and it is displaying the annual sea surface temperature of the Pacific Ocean (180° long.) and Atlantic Ocean (30°W long.) for the winter period.
Finally, in the fourth and last chapter are presented the conclusions of the analysis of the results and there is a discussion for the extreme values of the temperature of the anomalies.
