RedOrbit Meteorologist Joshua Kelly In this lesson we are going to look at special features which are found on weather maps. The map we are going to look at is from 500mb. That is roughly about 18,000ft above the ground. So to understand this map we need to go over the lines first. The solid black lines that are going from west-east are known as isoheights which are lines of equal height. At 500mb we label these lines using three digits. For example if you look over by Seattle WA,...

Joshua Kelly for Redorbit.com Red Orbit Meteorologist Joshua Kelly examines what makes up a weather station and how each instrument works. Here is a list of what type of equipment associated with a weather station. 1. Barometer: The barometer´s purpose is to measure outside air pressure. Air pressure can be recorded in MB or INS of mercury. Here is an example of each. -- 1013MB  or 29.92INS these are referred to as standard pressure of the atmosphere, when the numbers...

Surface Weather Map Features for July 5, 2012
2012-07-05 10:00:03

The morning weather map for July 5, shows us the current surface pressure readings. Surface Pressure is very important from a meteorological stand point. We use this to help us identify where our surface pressure centers are just like you see above. Our Low pressure area is over Northeast Colorado and also the High pressure over the Ontario area. Surface pressure is taken hourly from the stations and they are also mostly done on a 24hr basis, however some places will only submit their...

Upper Air Map Identification

Upper Air analysis is another important part of being a meteorologist and understanding how to read these maps is very important to our daily job. The above image is a 300mb chart that means this is the winds and temps at about 30,000ft above the ground. The first feature is over Western California. The darker blue shading is a jet maximum. What this means is that the winds are very strong over that region. It is possible for airplanes that are flying at that height to encounter...

Weather Map Identification

It is very important to understand what you are looking at when working with weather maps. In the image above we are looking at surface wind barbs. Surface wind barbs help us to identify which direction the wind is blowing and also the speed of the wind. If we look in the Northern Gulf of Mexico just to the south of Mississippi we see a wind barb in blue. This wind barb is from the East and it has two full wind barbs which tells us the wind is from the East at 20kts. If you look along...

Surface Weather Map Features

Looking at the weather map above we can see that we have three and four digit numbers on the map. These numbers are known as Sea Level Pressure. They are recorded in MB. Looking at the Northern part of South Dakota we see a number at 995mb while over parts of Maine we see the number closer to 1020mb. So we would say that high pressure is over Maine, while low pressure is over the Dakota’s as our MB numbers show. A surface pressure map can be very useful to a weather forecaster in many...

Important things to know when it comes to weather are the terms that a meteorologist uses on the television, radio or on a weather website.  The first term is Return flow. Sometimes you will hear a meteorologist use this term. The best way to understand this is to look at a weather map. When you see a High pressure center which is the blue H, look to the western side of that high pressure. This is where the warm moist air starts moving from the south back towards the north, which is why it...
