The soil, climate, and lack of trees made this area great for agriculture. Plants are cacti, mesquite trees, plains cottonwood, and several types of short grasses. The Llano Estacado is a flat, featureless grassland. Named by early Spanish explorers who came through the region in 1541. Llano Estacado is a Spanish term that loosely translates as "Staked plains". Llano Estacado is located on the southern end of the Western High Plains an eco-region The city is located on the Llano Estacado, one of the largest mesas in North America, that extends into Northwestern Texas and Eastern New Mexico. Lubbock is the countyĬhair of Lubbock County and is the biggest city in the South Plains of Texas. Lubbock is known as the "Hub City", because it is the economic,Įducational, and health-care hub of the multi-county region. Llano Estacado, at an elevation of 3,202 ft (976 meters). Lubbock Texas is located in the North West of the State of Texas and situated on the The city of Lubbock was incorporated in 1909. By 1891, a city government had formed, along with new churches and a jail. Lubbock county was formed in august of 1876. People west to settle the plains of Texas. The cattle boom along with cheap land prices brought more and more Spanish Exploration of the Great Plains (Photo Credit: nps.gov)Īfter the Civil War, more families moved to Texas looking for new lives, resources,Īnd adventure. Moses Austin, (whose son Stephen F Austin would eventually lead the Texas Revolution) asked permission from the Spanish Government to help settle the land, they approved and The French meanwhile had alsoīegun exploring North America and claimed much southeast. To explore and establish military posts and missions. By the 1730s the Spanish had sent more than 30 expeditions into Texas They brought with them horses that they traded The High Plains was in 1580 when the Spanish came across the area, remarking on the ![]() It and used all of its body for different resources. The buffalo was extremely important as they hunted Of the ancient dried-up lake that is today the caprock. Native Americans followed the large Buffalo herds that came to graze on the grasslands, Research to find traces of the earliest Texans continues." ( ) Now some scholars believe the story of humans here is even older –ĭating back 15,000 years or more. Rich remains from the Clovis culture, long believed to be the earliest to spread across 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."The earliest Texans, lived as hunters and gatherers, sharing the landscape with iceĪge animals including mammoths, cave lions, giant sloths, and dire wolves. 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.
