This is a compilation of worksheets that looks at how weather forms and creates long and extended climates.

Sometimes it is sunny, other times it rains, and at times it can get sticky hot out there. Weather is constantly changing minute to minute. For the most part, these changes are the result of changes in air pressure. Air pressure is a measure of all the molecules in the air that make up the atmosphere. When air pressure is lower cooling and cloud formation tends to happen. Which also increases the chances of rain. When air pressure is high it pushes air molecules to the ground, and this prevents clouds from forming. The worksheets found in this section work on the very basic direction in which weather moves after I is formed. You will find a wide variety of worksheets that show you how to understand forecast images and how they came to be.

Relative Humidity

The amount of water vapor that the atmosphere can hold at a specific temperature is called the relative humidity and is measured with a hygrometer.

Types of Fronts

The Atmosphere

Most of the exosphere is located in what we consider to be outer space, which is generally considered to begin between 50 and 80 miles from the Earth's surface.

QUESTIONS: The Atmosphere

The Earth's atmosphere consists of five main layers.

Droughts

Drought can be triggered in different ways. A large amount of reflected sunlight combined with more than the average number of high-pressure systems, winds containing continental as opposed to oceanic air systems, and ridges of high-pressure systems high in the air can all reduce the formation of thunderstorms or rain over a particular area.

What Causes Weather?

Weather significantly impacts our day-to-day activities. You wouldn’t feel comfortable wearing thin clothes on a snowy morning or walking to work without an umbrella on a rainy day. Hence, keeping yourself in sync with the latest weather updates is essential.

Weather is a combination of many atmospheric factors. This includes temperature and humidity, atmospheric pressure, and wind speed. While weather is specific to a particular locality, they are also affected by the weather in neighboring areas.

We have all experienced weather and its massive effects on our lives. Poor weather can change the way we interact with our environment and it can affect our moods and actions on a daily basis. We look at the forecast to determine how we should dress for our day and what we should do on our day. Extreme conditions can hurt us or in some cases bring us prosperity. Cloud formations can be used to predict what is coming our way. Any form of weather that continues endlessly can change what we do and where we did it. We have many tools available to us to understand climate and its patterns.

How do atmospheric conditions lead to different weather conditions? Is the weather constant, or is it fleeting? If you're curious, the following sections provide answers to these questions.

What Is Weather?

We were taught about the different types of weather in grade school. When the sun shines brightly throughout the day, we say we have a sunny day. When it’s dark and gloomy, it’s a cloudy day. And when it’s pouring hard, we know it’s a rainy day. From these examples, we know that weather is just the short-term condition of the atmosphere. 

Unlike climate, weather changes rapidly and is fleeting. Today could be scorching hot, yet it might rain cats and dogs tomorrow. This is why forecasters monitor the weather nonstop throughout the day. 

What Factors Cause Weather?

The main elements that describe weather are: 

  • Temperature 
  • Humidity 
  • Atmospheric pressure 
  • Wind speed and direction 

Precipitation, which also counts as an element that describes the weather, is a product of a mix of the previously mentioned factors. 

Technically, weather cannot take place without wind. The wind stirs and carries atmospheric components from one place to another. For instance, wind direction dictates where rain clouds end up, and wind speed tells us how soon they reach a specific location.

The sun's heat energy, measured in terms of temperature, has just as much to do with the weather as the wind. It leads to the evaporation of surface waters, causes wind speed changes, and gives meteorologists a clue about when and how much precipitation is expected.

When the humidity is high, the “real feel” temperature becomes higher than its actual value. This is because our sweat evaporates much slower, reducing our body’s capability to cool itself down. Hence, the weather feels hotter. 

It is also worth noting that while weather is specific to a particular locality, weather in neighboring areas also affects the weather in your region. For instance, when a storm currently ravages across Canada, neighboring states in the US may expect to experience stormy weather in the next few days. 

How Are Weather Forecasts Made?

To predict the weather, forecasters must first describe the current atmospheric conditions.

As such, they keep track of a set of indicators, including the factors mentioned in the previous section, continuously gathered 24 hours a day from weather stations, satellites, and ships scattered worldwide. 

The immense amount of data is then inputted into supercomputers found in weather forecasting centers and used as input in complex mathematical models that predict the behavior of a particular weather event. 

As the supercomputers continuously churn out predictions, meteorologists use their expertise and experience tracking weather to fine-tune the predictions made by the machine.

Conclusion

Weather is the short-term result of a mix of factors brewing in the atmosphere. Temperature, pressure, and wind speed are among the primary indicators that forecasters look at to predict weather daily.

It is worth noting that weather can change drastically from one day to another, or even in less than 24 hours. Hence, meteorologists work around the clock to distribute timely weather updates. 

We should regularly check updated forecasts to avoid getting soaked in the rain, suffering from the scorching heat, or having our properties damaged due to a lack of preparation for the weather ahead.
