Coming up with an accurate model can actually be equated to learning a secret language. It can be a very satisfying experience. On the upper-level and surface weather maps, the weather enthusiasts usually spot these station models. They normally play the roleof collecting all the important information from a number of stations present on a map. This is what makes the station model a very important tool. The good news is that it does not really take a lot to be able to come up with the model. All you will need is cursory weather knowledge and a basic understanding of the weather maps. Below are some tips and examples that you can use.
When the sky is only a quarter-way covered with clouds
Plot a circle then look at the sky and subdivide it into a number of eights. Fill the circle in line with the eights on the sky that you have created that have cloud cover. A clear circle is a representation of a station with no cloud cover while a full circle will represent a station with an overcast sky.
When the sky is overcast and has 65-knot average 1-minute wind speed
Draw a line from the circle going in the direction from which the wind is coming. Then draw a line long enough to be perpendicular and to and connect to the tip of the initial line; this should be representative of a wind speed of 10 knots. Then draw a second line that is shorter to represent a wind speed of five knots. Then draw a flag to represent 50 knots.
Find the dew point and the temperature of the weather station. To the left side of the wind barbs, make a recording of the temperature in degree Celsius. The dew point should be recorded just below the temperature; just under the circle but on the right side.
Slight but continuous rain during observation
To the left side of the circle that you had initially drawn, draw the symbol showing the current condition of the weather. Record the visibility in miles on the left hand side of the current weather symbol.
On the circle’s upper right side, jot down the sea level pressure. This pressure ought to be recorded to the nearest millibar tenth. On the weather station model, only the final three digits of the number should appear.
You should also record the changes in pressure. These changes in pressure ought to also be recorded to the nearest tenth. Jot it down just under where you have recorded the current pressure at sea level. A decrease in the amount of pressure should be signified using a negative sign while an increase in pressure ought to be signified using a positive sign.
To obtain maximum visibility, the weather authorities normally choose to use 7 miles. Ensure that the station that you are using has reference points to help you with the visibility.
Please remember that the average pressure at sea level is usually ranges from 930 to 1050 millibars. This means that when there is a recording of 298, it will be assumed to be 1029.8 and not 929.8. The only exception is usually when an abnormal weather event has taken place such as a very huge hurricane.
Making this model allows one to study whetherpatterns and be able to understand them at an advanced level. This is the main reason as to why it was earlier indicated thatone has to have cursory knowledge of the weather before they can start to draw the model. It isimportant that you be able to accurately read and measure the current weather conditions. Also important is having the knowledge of recording the different weather elementsand the units in which they ought to be recorded. For instance, you saw that pressure at sea level is measured in millibars while the speed of wind is measured in knots. For one to be able to accurately draw this model, you need to have knowledge of these things.
However, drawing the model is not as hard as it seems. It is actually a very enjoyable experience once you get to know the ins and outs of it.
