A rain gauge is used to measure how much rainfall has come. Farmers and gardeners whose crops depend on a certain amount of water to thrive. Uses a rain gauge to calculate how much water to add to the soil with its hoses or irrigation system. Meteorologists keep track of how much rain has fallen as part of the weather statistics for a region. This information helps to predict flooding and to determine how severe a drought is. Children often start learning more about weather instruments with a rain gauge because it is so easy to use.
In 1952 it rained
1,870 mm for a day in Chile, South America was it much or little? It rains differently in different places also in U.K. For example, it is usually wet in the western parts of the country. When it is dry in the rest of the country and vice versa. The amount of precipitation measured per day also varies over time.
Rain, snow and hail are three forms of precipitation. But also fog, dew and fog frost are counted as precipitation because they add water to the ground.
There are three different processes that lead to precipitation
Happens when the sun intensively warms up the ground and the air above the ground. The warm air rises up and brings along water vapor. The higher the air rises, the more it is cooled and eventually the steam condenses and forms rain clouds if the cooling is large enough. For example, convective rainfall occurs daily in the tropics over the rainforest or a really hot summer day in U.K.
Is due to the fact that clouds or humid air are cooled off as it is forced to rise. Because the terrain requires it. such as when clouds come in from the west over the Great Britain mountain range.
Is formed when two air masses with different temperatures meet. The warm and thus light air is forced to rise above the cold and heavy. The hot air mass is cooled and the water vapor in the air condenses and forms clouds. Front precipitation occurs, for example, when a warm and moist air mass from the tropics meets cold polar air.
Precipitation is always measured in mm
But you may want to know how much water falls on a specific area over a certain period of time. Ie you may want to express the amount of water that falls. In liters per square meter (l / m2) instead of in millimeters? The amount of rain measured in mm corresponds to the amount of rain expressed in l / m2. You can test how it gets by calculating the volume of rain. That has fallen over a certain area for a certain period of time. From the rain we measured up in our rain gauge (in mm) during the same time.
Put a rain gauge in the ground or install it on a pole. It is like a measure that fills with precipitation when it rains, sleds or snows.
One liter is the same as a cubic decimeter (dm3). So we want to calculate the amount of rain that falls in dm3 / m2 and time.
Read the correct rain gauge after it stops raining before the sun can cause any of the liquid to evaporate. Compare the point where the liquid in the rain gauge meets the scale on the side of the container. The number of brands where the top of the liquid touches the scale indicates how much precipitation fell.
A rain gauge
Is a must for the garden enthusiast. This different meter is handmade and has a glass container. That accurately measures up to as large a rainfall as 125 mm. It stands steadily without toppling over when it is put into the ground or in a flower box. Over time, the material gets a beautiful patina, but it does not rust.
Write down the measurement along with the date, time and type of precipitation. Keep a log of the measurements of your rain gauge. See if your measurements match the meteorologists. See if you notice any patterns or coincidences with record-high amounts of rain.
