THE WEATHER ENTERPRISE Part 1 Dr. Sam Miller Weather & Climate – MTDI 1200OL Plymouth State University 1
To sit in this seat: • You must understand meteorological theory • You must be able to apply this theory to draw conclusions about the real atmosphere • You must be able to communicate your conclusions to non-meteorologists in language they will understand • You must be able to do this under incredible pressure and time constraints
This means: • Quickly interpreting many kinds of observational data • Use of analyses of many kinds • Use of numerical aids, such as mathematical models • A constantly evolving 3-D image of atmosphere • SITUATIONAL AWARENESS • Cooperating with other scientists doing the same thing
ADVANCED WEATHER INFORMATIONPROCESSING SYSTEM (AWIPS) The Hot Seat
AWIPS helps integrate: • Observations from many different sources • Analyses of all kinds • Model (numerical) forecasts • Forecasts written by other meteorologists

DATA FROM MANY SURFACESTATIONS COMBINED STATION PLOT MODEL
DATA FROM MANY SURFACESTATIONS COMBINED STATION PLOT MODEL Temp Pres Dew Cloud cover
DATA FROM MANY SURFACESTATIONS COMBINED TIMES REFERENCED IN ZULU (GREENWICH)
DATA FROM MANY SURFACESTATIONS COMBINED Sea-level pressure (isobaric) analysis applied to the observed pressure data
DATA FROM MANY SURFACESTATIONS COMBINED Observations removed, leaving only the isobaric analysis
DATA FROM MANY SURFACESTATIONS COMBINED Animation of several surface charts with radar data (reflectivity) and frontal analysis added
DATA FROM MANY SURFACESTATIONS COMBINED Pretty color version with radar and satellite data added and surface observations removed (what we usually show the “civilians”)
Surface observations provide frequent updates of conditions at many locations on the Earth’s surface • The atmosphere is driven by forces that occur in three spatial dimensions • Need measurements in the vertical dimension
WEATHER BALLOONS FILLED WITH HELIUM OR HYDROGEN TRACKED BY RADIO DISH GPS ENABLED
WEATHER BALLOONS CARRIES AN INSTRUMENT PACKAGE CALLED A RADIOSONDE: Temperature Dew point (humidity) Wind direction & speed Barometric pressure Latitude and longitude Elevation
WEATHER BALLOONS RADIO TRACKING ANTENNA AUTOMATIC DATA RECORDER AND PROCESSOR
WEATHER BALLOONS OBSERVATIONS ARE REPORTED IN CODED FORM CALLED “RAWINSONDE REPORTS”
