King Fronts

A front is a mass of air. They come in various temperatures and forms.

A warm front is a front that has warm temperature. Before the front hits the winds blow south to southwest. The temperature is cold but slowly rising. There is light rain and poor visibility. The dew point is on a steady rise. During the front the wind is blowing in various directions. There is usually no precipitation but there may be a light drizzle. The visibility is improving and the dew point is staying steady. After the front the winds blow west to northwest and the temperature warms a bit then stays steady. There will be not precipitation. The dew point will rise then steady off. The visibility will be hazy or fair.
Below is a time lapse video I found on YouTube™ of a warm front passing over the area where the gentleman who filmed this lives. (May not load if you have slow computer)

Before a cold front comes along the temperature will be warm. and the winds will blow south to southwest. There will be short showers. The visibility may be hazy and the dew point will be high. During the front the winds will be gusty and shifting. There will be thunderstorms and heavy rain. The visibility will be poor but it will be improving. However the dew point will drop sharply. After the front the wind will be blowing west to northwest. The visibility is now good and the dew point is lowering.
A stationary front is a front that just stays in one place until it gets blown away or dissipates. A stationary front forms when a warm front and a cold front of equal strengths collide with each other and just stay in one spot.
occluded an occluded front is a front that is cool goes into a front that is cold and the cold air moves away, leaving room for the cool air to advance moving the cold air etc.

Below are some diagrams that demonstrate front symbols on a weather map.


-Data table
-3 2 liter bottles with the top cut off
-150 ml of water.
-Food coloring
-Saran wrap
First put 50ml of water into each bottle. Next with the food coloring make one bottle yellow and the other bottle will be colored a very very dark purple, keep the the last bottle clear for control. Once your bottles are filled tape the thermometer to the inside of the bottle being careful not to let it touch the water. Then measure the temperature of the water and record it in the table. Next turn on the light and turn on the stopwatch. Every two minutes record the temperature of each bottle and put it in the data table.Continue to do this until you have a sufficient amount of data.
