METR 2413 - Introduction to Synoptic Meteorology Introduction & Surface Observations University of Oklahoma 2004
Lecture Outline • Who am I? • What is this course all about? • Assessment: good news and bad news • Surface observations
Who am I? • Professor David Karoly, room 1366A, SEC dkaroly@ou.edu ph:325 6446 Office hours: Weds 11:30am – 1:30pm
What is this course all about? • Synoptic meteorology – an overview of current weather • Synoptic scale – larger than mesoscale - smaller than planetary scale - length scales ~300 - ~3000 km - time scales ~6 hours – 3 days
Arrangements • Monday – computing – Dr Laufersweiler • Wednesday – lecture – Dr Karoly • Friday – lab - Michael James TA • Web site http://weather.ou.edu/~metr2413/ • Prerequisites: MATH 2423 Calc II, PHYS 2514 Phys I, enforced • Textbooks: mainly for reference, do your reading assignements
Assessment: Good news and bad news • No final exam • Term project due Monday of finals week, 15% of final grade • Each week, computing assignment, homework, in-class lab (to finish after lab) (about 40 in total) • Announced and unannounced quizzes • 85% from linear combination of all these • Do all work on time, make-up allowances only in exceptional circumstances
Surface observations • Basic: temperature, humidity, pressure, wind speed and direction, rainfall (every 3 hours) • Visual observations: weather phenomena, visibility, cloud type, base • ASOS: Automated surface observing system www.nws.noaa.gov/oso/oso1/oso11/oso112/asos/sensrmap.html Replaced manual observing sites in NWS
ASOS • Tipping bucket rain gauge • Hygrothermometer • Present weather identifier • Wind speed and direction sensors • Ceilometer (Cloud height) • Freezing rain sensor • Thunderstorm sensor • Visibility sensor • Data collection package
Lecture Summary • Synoptic meteorology • An overview of current weather at scales of several hundred to several thousand kilmetres. • Assessment • No final exam, but a major project • Lots of homework; keep up to date!! • Surface observations • Representativeness of surrounding weather? • ASOS, manual obs
