Q: How do you read a weather forecast graph?
A: Weather forecasts such as those shown on TV often has colors and symbols to represent different types of weather around us. But what do those mean? What colors stand for what amounts of rainfall?
Well the answers to these questions sometimes depends on what weather channel you watch. The symbols may be the same but the colors may be different or the colors may be the same and the symbols may be a little different.Truthfully, in my opinion, it is a wiser choice to stick to your favorite weather program since all weather programs are a little different.
On the side is a graph of a forecast map and a picture telling you of the most commonly used symbols. Since it does not have the color key as well, I will go ahead and explain that to you myself. Usually green means rain and usually the darker the green is, the heavier the rain is expected to be. Also UV rays from the sun are shown by the colors green to bright pink most of the time. (Pink being the most UV rays.)

Types Of Equipment
Q: What types of equipment is used to forecast the weather?
A: There are many different types of equipment to forecast the weather and each one has its unique job to do. Some have to do with measuring temperature, wind, etc. Overall here are a few of the most popular and simple types of weather equipment: Anemometer, barometer, hygrometer, rain gauge, thermometer, wind sock, and weather vane.
The anemometer measures the wind speed and force of the wind. A barometer measures the low air pressure (when it is fixing to rain) and high air pressure (when it is dry). The hygrometer measures the moisture in the air around. A rain gauge shows how much precipitation (precipitation is snow, rain, hail, or ice) falls that day. A thermometer tells you the temperature in Centigrade and/or Fahrenheit. The wind sock shows the wind's speed and direction. The wind vane shows the wind's direction and is always recorded as the direction from which the winds are blowing.
As you can see, some of the instruments may do the same job but is a little more helpful than others while others may not be as accurate but shows two things at once. As example, the wind vane measures wind direction just like the wind sock (which measures both wind speed and direction) but the wind vane is more accurate. How? It shows the direct direction other than the general direction.

100% Sure?
Q: Can we ever be 100% sure of what to expect of the weather?
A: No! Of course not! Our weather equipment is accurate but it may make a mistake or two at times. Even though technology is advancing very quickly, our equipment is not quire on the spot yet. The weather can change direction, temperature, etc. without us knowing about it soon enough.
Have you ever turned on the news and the meteorologists would say that your city has no chance of the rain freezing the next day, then the next day it would snow really heavy? That is proof that sometimes our weather equipment isn't as dependent as we thought it was. Even though he said there was no possible chance of snow, the next day there was no way the meteorologist was correct.
However, this answer may change in the future. With technology growing, perhaps we will be able to be 110% sure of what to be prepared for the next day. For the present day right now, the only way to be 100% sure of what to expect of the weather is to go outside and experience the weather yourself.
