Is it really important for people to know the weather? For some, it’s just something that’s ‘good to know” because they can say “Rain or Shine – they’ll be on the go. However, there are some people whose daily activities rely on the weather. Farmers for example, needs to know the upcoming weather so they can tell if they’ll be planting or not. When there’s a predicted heavy rain, it wouldn’t be a good idea to plant seeds as it can get washed away.
For people with a normal routines, accurate forecasting of weather is important to help them keep safe. Nobody would want to go to the beach when there’s an upcoming storm, or no one would want to wear a jacket when it’s going to be extremely hot outside.
This is why it is very important as well to accurately forecast the weather. What meteorologists does is they capture details regularly on different parts of the world as the weather in one area may have slight to severe effect on the other area.
These forecasts and predictions are made possible by the use of a weather station. Weather stations uses several different instruments and equipment to guarantee accuracy of captured and recorded data. Accurate weather reporting is also important for weather broadcasting stations to maintain their reputation.
Here are some of the instruments commonly used in a weather station.
THERMOMETER – this is the device used to measure temperature. It is in fact also used to measure body heat to check if a person is suffering from fever, and how bad it is. There are several kinds of thermometer used in a weather station such as
Resistance Thermometer – this device is used by most weather stations because the temperature captured can be automatically logged to a computer. This also captures temperature faster than a mercury thermometer.
Mercury Thermometer – this device is also what’s used to measure body heat. It is made of glass cylinder with a scale and there’s mercury inside. The captured temperature is manually read.
Constant Volume Thermometer – this is said to be the device that captures the most accurate data and is used to calibrate information captured from other thermometers. However, this is not usually used in a weather station.
Bimetallic Strip Thermometer – this device is used is different applications like outdoor thermometers and thermostats.
BAROMETER–this is the device that measure atmospheric pressure which is the main indicator of the weather. As the atmosphere changes along with the air pressure, the weather changes as well. Short term weather changes are predicted by the meteorologists through the use of a barometer.
TRANSMISSOMETER – this is commonly used on stations or airports. It measures the unit of reduction of the light beam at a definite distance as it moves through air or water to be able to come up with independent measurement about current feasibility.
ANEMOMETER– this is the device in charge of capturing the direction and speed of wind and also the wind pressure.
RAIN GAUGE – from the name itself, it is used for collecting and measuring the amount of rainfall in a specific time period. This is almost always present in every weather station. Apart from weather forecasting, this is also used for climatology. The volume of rain collected can be read either by AWS (Automatic Weather Stations), or it can also be read manually.
WEATHER BALLOON–this balloon is typically filled with hydrogen or helium and is used to transport radiosondes to the atmosphere to help meteorologists with the study and prediction of weather.
BAROGRAPH–this device is a drum covered with by paper for an assigned time frame. It will result to a curve and that’s what’s called barograph. Barograph is usually instituted on ships. The data captured by this device gives precise signal of developments on the weather in the future.
LIGHTING DETECTOR – as the name suggests, this device is in charge of detecting light rays or lightning which is a product of storms.
WEATHER RADAR – this radar locates rainfalls, analyzes its route and evaluate their form. It is used to detect dangerous weather like heavy rainfalls, snow, thunderstorms, etc.
AUTOMATIC WEATHER SYSTEM or AWS – this weather station is situated on a movable or fixed spot and has sensors that automatically transmits data about weather. This is usually used on places that are either far away or hard to reach.
