Rudniak, Comparison of local solar radiation parameters with data from a typical meteorological year, Thermal Science and Engineering Progress (2019), doi. Received Date: Revised Date: Accepted Date:Ħ October 2019 4 December 2019 15 December 2019 There are two major types of rain gauges used in weather observations: a tipping bucket and a weighing rain gauge.Journal Pre-proofs Comparison of local solar radiation parameters with data from a typical meteorological year Joanna Rudniak PII: DOI: Reference: The rain gauge measures the amounts of water that falls at a particular time. Precipitation is measured with a rain gauge. These are the common weather elements and the common instruments used in measuring them. Elements of Weather and the Instruments used in their measurements Wind – is the air in motion that moves from areas of high air pressure to those of low air pressure, wind occurs due to rising hot air or sinking cold air.For instance, coastal regions and islands on a daily basis experience severe storms as a result of nearness to water bodies. Changes in atmospheric pressure are mostly caused by the rise of warm air and the descent of cold air hence, atmospheric pressure occurs mostly in regions near water bodies. Atmospheric pressure – the atmospheric pressure is the “weight” of the air in the atmosphere.

For instance, lighter cloud indicates little or no precipitation, while dark heavy cloud indicates that the will be heavy rain or thunderstorms. Different types of clouds mean different weather conditions.

  • Cloudiness – this is simply the state of clouds in the atmosphere in a given time over an area.
  • However, humidity is the prolonged moisture level of an area that can affect an entire ecosystem. It can be used to predict a coming storm. The humidity is an element of weather that can influence the day by making it feel hotter humidity.
  • Humidity – is simply the amount of water vapor in the air or in the lower atmosphere.
  • However, the temperature is an important element of weather and influences other elements such as wind, humidity, precipitation, atmospheric pressure, and clouds. Increased temperature is determined by the angle of the sun hence, the temperature may change repeatedly within a day.

    Temperature – temperature measures the degree of hotness or coldness of a place from day-to-day.As an element of weather, precipitation determines whether outdoor activities are suitable and it can easily be predicted by observing the signs in the sky. The forms of precipitation include rain, snow, fog, mist, hail, sleet, and drizzle.

    This falls after the cloud has been formed in the sky.

  • Precipitation – precipitation is a form of water in the atmosphere that falls to the earth it is formed as a result of rapid condensation of moisture.
  • They are what bring about sudden atmospheric changes. Elements of weatherĬommon elements of weather include Precipitation, temperature, humidity, cloudiness, atmospheric pressure, and wind. Weather changes on a daily basis it could be minute by minute, hourly, daily, weekly, monthly or yearly, while climate changes after a long period of time, hence, climate change is the rise in average weather condition over time and space. The climate is defined as the average weather condition of a place over a given period, usually over 30 years.

    This is not the same as climate which takes place over a long period of time. Therefore, is simply a day-to-day temperature and precipitation conditions that take place in a given surrounding. Weather conditions make it possible for us to see, feel, and detect each time the changes occur, especially in our immediate environment. This is defined as the condition of the atmosphere at a given time it is simply seen as the degree at which a place is hot or cold, wet or dry, clear or cloudy, and calm or stormy. It also influences the type of food we eat, the cloth we wear, the places go and where we live. Whenever one hears the word “ weather“, what should come to the mind should be sun, rain, wind, pressure, humidity, or cloud. One can easily detect the changes in the atmosphere whenever they occur, in this case, we can boldly say that the weather has much influence on man and his activity. These experiences are obvious, even without much observation. Weather is what we experience in our immediate environment on a daily basis.
