  1. Jordan Meteorological Department (JMD) Enhancing South West Asian Climate Change Monitoring and Indices Alanya, Antalya 4 to 9 October 2004

  2. Area total: 92,300 sq km land: 91,971 sq km water: 329 sq km 26 km coast line lowest point: Dead Sea -408 m highest point: Jabal Ram 1,734 m mostly desert plateau in east, highland area in west; Great Rift Valley separates East and West Banks of the Jordan River

  3. JMD Network • Main stations (22) *SYNOPTIC & AGROMET STATIONS • Volunteers (27 ) *CLIMATE STATIONS • Rainfall Stations (60) * • These rainfall stations run by different agencies • The data is not digitiz • The data is used for media purposes Daily, monthly & synoptic (6 hours) data available in digital format

  4. Station Information

  5. Data collection and processing • National Forecasting Center • The raw data are received from Global and Regional centers • Satellite and Radar Data are also received. • Manual data decoding, plotting analysis and forecasting • NWP-models are used to Issue 24-72 hours weather forecast • Applied Meteorology Directorate • Collecting Data from station networks • Climate elements ( Temperature,precipitation, upper air …..) are observed@ (00,03,06,09,12,15,18,21 GMT) • Processing data from station networks • Archiving • Distribution of Climate information

  6. Climate Data management module Data source Data Processing archiving Station sites • Long term • Retrieval • Collecting ,checking • Readable format • QC-procedures • Input in database CDBMS’s JCDMS 1.1 OUTPUT

  7. Presentation of climate data • Tabular and Graphical • Maps • Standard publications

  8. Jordan climate Major characteristic:- • Rainy season (November to April )and very dry weather for the rest of the year. • Hot, dry, uniform summers and cool, variable winters during which all of the precipitation occurs. • Jordan has a Mediterranean-style climate.. • Jordan long summer reaches a peak during August. • January is usually the coolest month. • Wide ranges of temperature during a twenty-four-hour period are greatest during the summer months .
