Elements of weather and climate pdf

Even though you don't recognize it, you also experience the effects of humidity and atmospheric pressure. Well, you just experienced 3 of the elements that make up weather and climate. Let's first quickly the elephant in the room for many of you. Yes, there is a difference between weather and climate. You can read all about it here. But the elements that make up both are the same.

When I talk about weather elements throughout this article, you can safely assume that, for the most part, I include climate in the discussion. It's just faster and less repetitive to refer to weather only for the purpose of this post. As you would have guessed by now, in this article, we look at the different elements that make up the weather. We will examine what they are, define each component, and also look at the instruments that measure each element.

Weather is nothing more than the different elements it is composed of, as well as the way they interact with each to create different atmospheric conditions or weather events. Before we can discuss them in detail, we first need to identify what the elements are that make up the weather.

We all know what temperature is. When discussing the weather, this will probably be one of the first topics that come up. It is because we are so sensitive to temperature and quickly become aware of feeling cold or hot. Temperature is a measurement of the amount of kinetic energy present in the air, which manifests itself physically through the experience of heat or cold.

The scales typically used to measure temperature are Celsius, Fahrenheit, and Kelvin. The instrument used to measure temperature is called a thermometer. In more practical terms, it means that the particles in the air move or vibrate at a certain speed, which creates kinetic energy. When the particles begin to slow down, the temperature also starts to decrease. The thermometer is the instrument used to measure temperature.

They come in all shapes and sizes and date all the way back to The mercury, bimetal, and digital thermometer are the 3 most commonly used instruments for measuring ambient temperature. If you want to learn more, you can get more detailed information about the different thermometers and how they work in the following article. Air pressure is another essential element of weather, especially when it comes to creating or changing atmospheric conditions.

It is also one of the critical variables used to make accurate weather forecasts. Air Pressure is the result of the pressure created by the weight of the air in the Earth's atmosphere.

It is also called barometric pressure, named after the instrument used to measure air pressure. Although it may not be visible, air has weight since it is not empty. It is filled with small particles of nitrogen, oxygen, argon, carbon dioxide, and a few other gases.

The weight of the particles in the air creates pressure due to the gravitational force of the Earth. Since more air is present above the air close to the ground, air pressure is the highest on the planet's surface and decreases as altitude increases.

The barometer is the instrument used to measure air pressure. Evangelista Torricelli developed the first device in Like the thermometer, the barometer also comes in different forms. Some examples include mercury, water, aneroid, and digital barometers. If you need more information, you can find in-depth information about the different types of barometers, how they work, as well as their history in this article. The movement of air wind is one of the main driving forces of weather.

Wind is the large-scale movement of air from an area of high to an area of low pressure in the atmosphere. The speed and strength of wind are determined by the distance between the low-pressure and high-pressure areas, as well as the difference in air pressure. Everyone has a pretty good idea of what wind is, so no need to go into more detail here. If you want to learn more about what exactly wind is, how it is formed, and its impact on the surroundings, you can find it in this article.

The anemometer is the instrument used to measure wind speed. Consisting of half-cups on arms rotating around a central axis, you can typically find it on top of a weather station or at an elevated position. A wind vane or weather vane is the instrument used to measure wind direction. It is a flat-shaped object that spins freely on an axis. Very often, in the shape of an arrow or cockerel, you can also find it on top of a weather station or highly elevated objects.

It is common to see them on top of roof chimneys, church towers, and even communication towers. If you need to, you can find more information about anemometers and wind vanes in the same article mentioned in the previous paragraph.

Humidity is another weather element that cannot be seen but can be felt. It not only plays a big part in weather formation but also directly influences our physical comfort levels. Humidity is the amount of water vapor that is present in the atmosphere at any specific time. Water vapor is nothing more than water in a state of gas after the liquid has evaporated. Although humidity and its effects can usually be felt, it is normally invisible to the naked eye.

Humidity can be challenging to understand and interpret correctly. Then you also have to be able to make a clear distinction between absolute and relative humidity. The subject is too comprehensive to cover in this post, but you can read the in-depth article covering humidity in detail here.

The hygrometer is the instrument used to measure wind speed. Please allow access to the microphone Look at the top of your web browser. If you see a message asking for permission to access the microphone, please allow. Advanced search.
