Résumé
In this study, drought monitoring in Jordan is studied by several drought indices, the SPI is consistent a good index for Jordan, and the results is used in Mann-Kendall trend analysis for 3, 6, 12 and 24 month time scale to find the trend in wet and dry (increasing or decreasing in precipitation) conditions in Jordan. The results of Mann-Kendall trend analysis are found no significant trend in 3, 6, 12 and 24 month time scale except in two stations. In order to have better understanding of drought situation in Jordan, a new approach is used Precipitation-Month method for SPI series for 3, 6, 12 and 24 month time scale and for several truncation levels. This is considered a new approach in drought analysis and it is results is given in detail for several truncation levels. The wetness and dryness (increasing or decreasing in precipitation amount) conditions of each truncation level are determined for 3, 6, 12 and 24 month time scale. In general the results indicate some stations have increasing in precipitation and some stations have decreasing in precipitation.
