Overview

The general objectives of the course are written in the form of outputs that the student is supposed to acquire after successfully completing the course:- Introducing meteorology and its many branches with different characteristics, whether basic or applied.- Understanding the gaseous and non-gaseous components of the atmosphere, their percentage, and their importance in the process of the Earth's thermal balance, and understanding the four layers of the atmosphere, with a focus on the troposphere layer close to the Earth's surface.- Study the various elements of the atmosphere such as: atmospheric pressure, air density, temperature, water vapor with an understanding of the process of thermal equilibrium, the extent of daily change in temperature, the rate of dry self-enthalpy and also the rate of saturated autoenthalpy.- Knowledge of the stability and instability of the atmosphere through the general theory of stability and also the relationship of the rate of thermal decrease of the rising air and the rate of thermal decrease of the prevailing atmosphere with the stability of the atmosphere. Geostrophic winds, downhill winds, and the fog phenomenon.

Intended learning outcomes

a. Knowledge and understanding:1. The student should describe the basic and applied branches of meteorology.2. The student should identify the gaseous and non-gaseous components of the atmosphere and enumerate the layers of the atmosphere from the earth’s surface to its end, with a description of the characteristics of each layer.3. The student will be familiar with the elements of the atmosphere and describe the characteristics of each element separately. The student also explains the thermal equilibrium process and the dry and saturated self-decreasing rates.4. The student should explain the relationship of the stability of the atmosphere or not to the rates of temperature decrease of the rising air and the ambient air. It also recognizes the characteristics of the elements of the atmosphere - wind and fog.B. Intellectual skills:1. That the student compares the functions of the different branches (basic and applied) of atmospheric science.2. The student should distinguish between the layers of the atmosphere in terms of thermal and physical properties, while analyzing its gaseous and non-gaseous composition.3. That the student relates the changes that occur in the elements of the atmosphere: atmospheric pressure, temperature, density and daily rates of change for each element. It also compares the dry autoenthalpy rate and the saturated autoenthalpy rate.4. To compare the circumstances of the occurrence of instability and states of stability in the atmosphere, and what is concluded from both cases, while studying the relationship to the elements of the atmosphere, wind and fog.C. Practical and professional skills:1. The student should perform extensive desk research that helps him understand what is happening in the atmosphere and distinguish between the functions of the basic and applied branches of meteorology.2. The student should store in his memory the characteristics of each layer of the atmosphere for use in practical applications.3. The student should use basic information from what he understood of the elements of the atmosphere and the different rates of temperature decrease to explain the continuous changes that occur in the atmosphere.4. The student clearly diagnoses the conditions of stability and instability in the atmosphere and the weather conditions that accompany them.D. General and transferable skills:1. The student should be able to use information technology to obtain multiple sources related to the branches of atmospheric science.2. The student should be able to think about the importance of different weather elements and link them to determine the type of local weather.3. The student should be able to communicate with the scientific authorities and global meteorological agencies, written and orally, in both Arabic and English, in order to understand the conditions of stability and instability in the atmosphere.
