This volume is addressed to first year students, Open Distance Learning and Low Frequency Education, who, animated by the natural desire to broaden their horizons of knowledge, as well as the equally natural one, to increase the chances in the current competition for employment in the field of geography, they decided to use the opportunity offered by this modern form of education, through which they will be able to obtain the real and legal qualification to participate in the respective competition. It is one of the numerous textbooks that provide the basic bibliography for the training of students in each of the disciplines included in the study program developed by experienced geographers belonging to the University of Bucharest. Its substance consists of the essential problems of the two fundamental disciplines that give it its title: Essential in Meteorology and Climatology.
According to the strategy developed for distance learning and part-time education, which could not omit the difficulties encountered by students in finding the time resource and procuring the learning resources necessary for adequate training, this manual, like all textbooks in the series part, provides students with the essential knowledge for an accurate understanding of how atmospheric systems work in the complex whole of the terrestrial system.
The effort of essentialization, consisting in selecting the basic problems and explaining the mechanisms of the processes and atmospheric and hydrosphere phenomena decisive for the functioning of the respective system, is doubled by the one destined to accessibility of often arid and unattractive knowledge for a good part of the students. The latter effort refers to the attempt to ensure the maximum clarity of the language used in defining notions, legalities, etc., in highlighting causal links, in ranking the factors that generate various processes and determine their evolution, in identifying their consequences for other processes and areas, etc. .
Accessibility and efficiency are also pursued by the form adopted by this manual and all other manuals in the series. And the form wants to be relaxed in the essentialization and systematization of the material, trying to stimulate and facilitate learning by establishing the objectives of each chapter, by formulating questions and answers with different degrees of difficulty, by emphasizing some essential processes and phenomena, some legalities, some superlatives etc.
The option for such a scientific level of presentation of the Meteorology and Climatology textbook is based on the relationship between accessibility and efficiency in the real context of its addressability. Because a higher level could determine, for those to whom it is addressed, a decrease in accessibility, and a lower level would entail a decrease in efficiency.
If the authors' thoughts were well balanced and correctly transposed in the textbook, it remains to be seen. Those who will be the first to know this are, of course, the users.
