The 1990s and 2000s saw redevelopment in numerous city neighborhoods, including Downtown. Beginning in the 1950s, Columbus began to experience significant growth it became the largest city in Ohio in land and population by the early 1990s. Amid steady years of growth and industrialization, the city has experienced numerous floods and recessions. The city assumed the function of state capital in 1816 and county seat in 1824. The city was named for Italian explorer Christopher Columbus. The city was founded in 1812 at the confluence of the Scioto and Olentangy rivers, and laid out to become the state capital. Franklinton, now a city neighborhood, was the first European settlement, laid out in 1797. It had a population of 2,138,926 in 2020, making it the largest metropolitan area entirely in Ohio and 32nd-largest metro area in the U.S.Ĭolumbus originated as numerous Native American settlements on the banks of the Scioto River. It is the core city of the Columbus metropolitan area, which encompasses ten counties in central Ohio. Columbus is the county seat of Franklin County it also extends into Delaware and Fairfield counties. state capital after Phoenix, Arizona and Austin, Texas. With a 2020 census population of 905,748, it is the 14th-most populous city in the U.S., the second-most populous city in the Midwest after Chicago, and the third-most populous U.S. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall. 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. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
