Overview

1. Introducing students to the process of measuring atmospheric variables or elements, classification of meteorological meteorological devices, methods and mechanism of recording meteorological devices, features and characteristics of the meteorological device. Also the meteorological station and its various devices. 2. Familiarity of the student with the working mechanism of the atmospheric pressure gauges and the various air temperature gauges, as well as the methods of measuring each of these two elements.3. Introducing the element of atmospheric humidity (water vapor) and the devices used to measure it, such as: sychrometer with natural ventilation, rotating psychrometer with artificial ventilation, hygrometer, hygrograph, the process of condensation of water vapor in the atmosphere. Also, an understanding of the working mechanism of wind speed and direction measuring devices such as the propeller anemometer, precipitation measuring devices and evaporation measuring devices.4 . Familiarize students with the process of measuring the number of hours of sunshine and measuring the amount of solar radiation and the devices used for this purpose. Also, methods for measuring the height of the base of the tow.

The student should explain how to measure atmospheric pressure using the mercury barometer and the metal barometer. Also measure the air temperature (minimum, average, maximum) using a mercury thermometer and an alcohol thermometer.3. That the student explain the concept of measuring atmospheric humidity and the many methods for calculating it and the devices used for this purpose, the method of condensation of water evaporation in the atmosphere. Also how to measure the speed and direction of the wind, the amount of precipitation and the devices used to measure both elements. Calculate the amount of evaporation from water surfaces.4. The student should familiarize himself with the devices for measuring the number of hours of sunshine and the general concepts of measuring solar radiation. Also, how to measure the height of the cloud base and the methods used in that.B. Mental skills:1. The student should compare the results of the readings of several devices for the same air component to find out the error percentage in the devices used and calibrate them.2. The student analyzes the mechanism of action of the mercury barometer for measuring atmospheric pressure, as well as the mechanism of action of the mercury thermometer for measuring air temperature.3. That the student relates the process of evaporation in the atmosphere, the process of condensation of water vapor in the atmosphere, and the process of precipitation.4. The student should distinguish between the amount of solar radiation and the number of hours of sunshine per day.c. Practical and professional skills:1. The student performs the task of classifying meteorological devices and checking them periodically at meteorological stations.2. The student should distinguish between devices for measuring atmospheric pressure (the mercury barometer and the metal barometer). It also distinguishes between temperature measuring devices (maximum temperature thermometer, minimum temperature thermometer, dry temperature thermometer, wet temperature thermometer, soil thermometer).3. That the student memorizes in his memory the working method of two devices measuring the amount of moisture in the atmosphere (the cyclometer with natural ventilation, the rotating psychrometer with artificial ventilation) and also the method of working of the device for measuring the speed and direction of the wind (the anemometer with a fan).4. The student should diagnose the outputs of measuring the number of hours of sunshine and solar radiation using a number of devices and compare the results of the diagnosis.D. General and transferable skills:1. The student should be able to use information technology to obtain information related to meteorological elements, classification of meteorological meteorological devices, and the mechanism of action of various meteorological meteorological devices.2. The student should be able to maintain the exact time selection when measuring atmospheric elements due to their extreme importance in the credibility of the meteorological process, such as atmospheric pressure and air temperature.3.
