National <br />Weather Service personnel developed this program to perform in- <br />depth analyses of data obtained from rawinsondes they launch twice <br />a day, generally one at 7 a.m. and again at 7 p.m. On the WKWM <br />Programl rawinsonde data from Dodge City are indispensible to making <br />a good short-term forecast for the next 12, or more, hours. SHARP <br />lets us look quickly into important atmospheric characteristics. <br />Rawinsondes are balloon-borne instruments which contain sensors <br />measuring pressure, temperature and humidity changes which are <br />transmitted by radio signals to the ground station tracking it. <br />Windspeed and direction with height are also found. <br /> <br />Radio and television weather programs can provide a general <br />indication of expected storm development within the _operational <br />area. Unfortunately, media information is insufficient in detail <br />to successfully conduct an operational weather modification program <br />in real-time. A small TV set in the field office does provide <br />access to the regular three networks' weather updates, advisories, <br />alerts and occasional real-time Doppler radar displays during storm <br />periods. Background monitoring any of the network broadcasts <br />during severe storm operations is usually helpful as their staff <br />exhibits a high degree of professionalism in providing the viewing <br />public timely, important and relevant severe weather information. <br /> <br />The best weather-related TV program is The Weather Channel, a <br />24-hour-a-day, non-stop weather program providing periodic radar <br />and satellite, forecasts and general analyses and regional surface <br />observations. Where the WK\'M field office is located, it is unable <br />to receive The Weather Channel, except at prohibitive costs, but <br />WKm1 personnel generally monitor it when at home. Fortunately, at <br />least two new satellite-based services for agriculturally-related <br />financial interests have sprung up relatively recently. Within the <br />menu of the services provided are a variety of weather-related <br />programs very useful to us. <br /> <br />One such service is the Data Transmission Network (DTN); it <br />was tested early in the season and found to be highly useful to us. <br />DTN offers a variety of radar composites which can be displayed in <br />various ways and even allows the user to interact with it so the <br />user can modify a given program to his preference. For example, a <br />desired area of interest can be enlarged for better viewing a <br />composite of radar data, along with a looping of radar data <br />broadcast earlier the past few hours. Similarly, satellite data <br />can be looped and zoomed, if desired. Although it cannot be relied <br />upon for accurate local radar data, it is useful to monitor the <br />surrounding regional picture from that part of Kansas east of our <br />target area then north to Nebraska, west to Colorado and south to <br />New Mexico, Oklahoma and Texas. Routinely, each day, we could see <br />how and where storms would develop outside the normal radar viewing <br />area and be alerted to the possibility that our area may likely <br /> <br />14 <br />
