![]() Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). "Reflectivity" is the amount of transmitted power returned to the radar receiver. Often, the most visually compelling video of severe weather is from a safe distance, which is what we always strive to achieve.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. It is also important to remember that we have a very powerful zoom lens on the rooftop camera that allows us to make storm clouds that are 15 miles away look like they are right outside the window. But more accurately, we stay ahead of the storms! If you are chasing storms, then you are already too far away! In order to properly cover severe storms, you must always stay ahead of them while avoiding their path. This made her question “why weather happens.” Do we chase storms? Her dad’s childhood home in Chesterfield was destroyed by the F4 tornado of January 1967 that ripped through Chesterfield, Creve Coeur and Maryland Heights of St. Her interest in weather developed from her fascination with tornadoes. Jaime Travers can be seen on television in St. You can see Angela Hutti on FOX 2 on Friday and Saturday evenings. He has a lifetime of experience with our wild weather and will never forget the bitter cold winters of the late ’70s, the “Blizzard of ’82”, the “Drought of ’88” or the “Great Flood of ’93”. With the weather constantly changing, we must adapt and adjust as meteorologists.”Ĭhris Higgins was born and raised here in the St. Louis area weather figured out, a new wrinkle develops, like the 2012 drought or Spring 2013 tornadoes.
