Introduction to meteorological instruments and atmospheric pressure is a free online course that has been specially prepared to teach you about shipborne meteorological instruments. When working with shipborne meteorological instruments, you should take the time to learn about its precautionary measures. If you are asked about measuring the weather, you should know that weather maps are useful for indicating the atmospheric conditions of various portions of the earth’s surface. Some weather variables produce environmental conditions which form a chain reaction, but may not remain entirely in the atmosphere. Do you know that temperature, pressure and humidity (moisture) can interact to form clouds? If you try to take your ship out without understanding the atmospheric conditions, you will be risking your life and shipping vessel. Prepare yourself to learn about the aneroid barometer, Stevenson’s screen, whirling psychrometer, and different types of hygrometers when measuring atmospheric pressure, as well as relative humidity.

If you want to learn about the seawater temperature bucket, as well as the procedures for using it to measure sea surface temperature, then you should complete this course. You will also be able to identify the various layers of the atmosphere starting from the ground level. The layers of the atmosphere include the troposphere, stratosphere, mesosphere, thermosphere and exosphere. This course can also help you analyze the environmental curve, as well as the environmental lapse rate (ELR). You will also be able to learn about temperature inversion and the classification of the atmosphere. Do you know that there are certain losses in solar radiation? To learn about these losses, you will also need to understand the modes of heat transfer and how heating happens in the atmosphere. It is also important that you learn about the factors that influence the heating effect. If you want to learn about insolation, you will need to learn about evaporation and condensation.

Furthermore, you can also learn about vapor pressure changes and how vapor pressure is applied to a liquid. Do you know that absolute humidity and relative humidity are not the same? You will learn about their differences, along with the formula for calculating relative humidity. You will also learn about a typical isobaric pattern, isallobars, and barometric tendency. Estimating the type of weather to expect is important to a navigator, but you will need to learn about the barometric tendency characteristics. If you do not complete this course, you will lack vital knowledge about handling shipborne instruments. You will also need to complete this course if you want to know how to calculate different atmospheric conditions. This free online course will be of great interest to students, researchers, and anyone with an interest in understanding the atmosphere and shipborne meteorological instruments. So, register for this course and start your next learning journey today.
