BiologieTags : Climat Précipitations Est algérien Températuress Quotient pluviothermique d'Emberger Analyse en composantes principales Temperatures Precipitations East Algerian Climate EMBERGER’s pluviothermic quotient Principal Components Analysis Index. décimale : 570 Sciences de la vie. Biologie Résumé : In Eastern Algeria, precipitation and temperature are characterised by a great variableness, be it in time (yearly or monthly) or in space. To define and explain this variableness, two periods of observation (1913-1938 and 1978-2004) and 27 meteorological stations and post are used.
The analysis of the pluviothermic quotient and EMBERGER’s climagramme for these two periods shows a vertical sliding of bioclimatic floors in coastal stations and a horizontal slide in inland ones.
Finally, a headword average mobile analysis is carried out on series of monthly average temperature and monthly total precipitation. The main parameters allowing to sum up these series are put in a prominent position, and the analysis of the major components of these parameters allows the classification of most weather characteristics in the region under study.
This classification solves the dilemma often faced by bioclimatologists, which is the use of most climatic variables without limiting them to their simple expression (their average for example). The aim is to analyse this spatial and temporal variableness and to show the link between the separative and synthetic methods.Diplôme : Magistère En ligne : ../theses/biologie/TIR5572.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=1823 Climagramme d'Emberger : Analyse et correction dans quelques stations météorologiques de l'Est algérien [texte imprimé] / Kamel Tir, Auteur ; Université Mentouri, Editeur scientifique ; Med EL Habib Benderradji, Directeur de thèse . - 2009 . - 99 f.

The hills of Constantine which is a part of northern Algeria, where physical and human conditions (type of vegetation, climate, relief ...) are combined to favour this scourge.
With the climate changes observed in recent decades, the forest fires have increased and are seriously threatening the forest ecosystems.
An analysis of the evolution of climatic data for the previous and current period as well as the released water balance highlights in the recent decades (1980 - 2012), an increase of the temperatures and a decrease of rainfalls, which were Among other causes that have increased the frequency of forest fires.
The consequences of forest fires are apparent in the region, the transformation of landscapes is present everywhere, it allows to understand the extent of shrinkage of the forest area; the maquis, which continue to expand, express the degradation of the forest cover.
Forest fires can be minimized only through a prevention which is based on risk assessment, and is the only way to reduce the cost of damages caused during major forest fires.
