This article thoroughly explained the eight elements that make up the weather, what they are, and which instruments are used to measure each one. Campbell–Stokes recorders basically consist of a spherical lens that focuses sunlight on a specific type of tape to make its measurement. Sunshine recorders, more specifically Campbell–Stokes recorders, are the instruments used to record sunshine duration.

This ability makes it a more powerful and influential factor than you might think. It not only plays a big part in weather formation but also directly influences our physical comfort levels.Īs already stated, sunshine duration influences other weather elements, which can change the whole makeup of the weather conditions. Humidity is another weather element that cannot be seen but can be felt. If you need to, you can find more information about anemometers and wind vanes in the same article mentioned in the previous paragraph. It is common to see them on top of roof chimneys, church towers, and even communication towers. 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 a flat-shaped object that spins freely on an axis. The anemometer is the instrument used to measure wind speed. Consisting of 3-4 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.Ī wind vane (or weather vane) is the instrument used to measure wind direction. Instruments For Measuring Wind Speed And Direction 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 majority of major and even extreme weather events like cold & warm fronts, clouds, thunderstorms, and hurricanes are all driven by wind.Įveryone has a pretty good idea of what wind is, so no need to go into more detail here.

The movement of air (wind) is one of the main driving forces of weather. 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. Some examples include mercury, water, aneroid, and digital barometers. Like the thermometer, the barometer also comes in different forms.

The barometer is the instrument used to measure air pressure. Evangelista Torricelli developed the first device in 1643. 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 weight of the particles in the air creates pressure due to the gravitational force of the Earth. It is filled with small particles of nitrogen, oxygen, argon, carbon dioxide, and a few other gases. Eight primary elements/factors drive all weather:Īlthough it may not be visible, air has weight since it is not empty. 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.īefore we can discuss them in detail, we first need to identify what the elements are that make up the weather. What Are The Elements Of The Weather And Climate? We will examine what they are, define each component, and also look at the instruments that measure each element. It's just faster and less repetitive to refer to weather only for the purpose of this post.Īs you would have guessed by now, in this article, we look at the different elements that make up the weather. When I talk about weather elements throughout this article, you can safely assume that, for the most part, I include climate in the discussion. But the elements that make up both are the same. Yes, there is a difference between weather and climate. Let's first quickly the elephant in the room for many of you. Well, you just experienced 3 of the elements that make up weather and climate. Even though you don't recognize it, you also experience the effects of humidity and atmospheric pressure. At any point during your day, you experience temperature by feeling hot or cold.
