![]() 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. ![]() ![]() It covers an area of 120,000 square milesroughly the size of New Mexico. Tamu Massif is an extinct volcano in the Pacific Ocean, around 1,000 miles east of Japan. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. The world’s biggest volcano has lost its title after scientists discovered it formed via seafloor spreading rather than a single eruption. 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. 2 Black Mesa Oklahoma Mountain Updated: Black Mesa is a mesa in the USA states of Colorado, New Mexico, and Oklahoma. 64 (south of the town of Felt), Rita Blanca WMA is a shortgrass prairie. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). Rita Blanca WMA Map WMA Legend Rita Blanca WMA covers 15,575 acres of southwestern Cimarron County in the Oklahoma panhandle. "Reflectivity" is the amount of transmitted power returned to the radar receiver. No camping is allowed in the preserve, but there is a campsite nearby at Black Mesa State Park, about 9 miles away along OK 325.Ĭheck out the Official Route and Triplogs.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.

Find high-quality stock photos that you wont find anywhere else. Sign in, enjoy the top, and make your way back the same way you came. Map Description: 'Somewhere out in the vast expanses of the New Mexico desert, the Black Mesa Nuclear Testing Team decided to hide a big red button. Search from Black Mesa Oklahoma stock photos, pictures and royalty-free images from iStock. Keep hiking until you see the large granite monument that signals the highpoint of Oklahoma. To reach the true highpoint, there is still a little over a mile to go, but it's now flat again. This is where the views are best: certainly more so than from the highpoint on the mesa ahead. The vegetation is more sparse here and you are more exposed to the wind, which might feel refreshing on a hot day. Your directions start from Duncan, OK, USA and end at Black Mesa State Park. Continue an ascending traverse to what is now a west-facing slope, and finish your ascent on the mesa top. The Google map above shows directions from Duncan to Black Mesa State Park. When you reach the bench for Mile Marker 3, you're near the top of the climb. ![]() This is where you gain the majority of the elevation for the day - 500 feet over the next mile - first cutting up a side canyon, then hiking up some switchbacks. At the bench for Mile Marker 2 (Route Scout clocked it in at 2.2 miles), the trail swings south and heads straight for Black Mesa, and you can see the trail cutting up the slope ahead, signaling your imminent ascent. Thank goodness for the states 'panhandle,' a 166-mile-long strip of land extending west toward New Mexico, which gives the. Their mileage didn't quite align with the mile markers noted using Route Scout, but they do provide decent shade and views of the desert surroundings. Oklahoma comes very close to being a boxy nonentity on the national map. You will pass a couple of benches that have mile markers etched on them. Occasional junipers provide shade and you'll see some washes beside the trail. The first two miles are pretty tame, as you gain minimal elevation hiking along the north side of Black Mesa proper on an old two-track. There's a pit toilet at the trailhead and a gate that you'll walk through to start the hike. Black Mesa itself looms directly above, but the true summit within Oklahoma is still a few miles away. The hike starts from the large dirt parking lot at the trailhead.
