Phytoplankton Population Changes in Lake Urmia During Dry and Wet Periods

Changes in Moisture entering the atmosphere of Iran and its relationship with seasonal wet and dry periods

Spatio-temporal variations of factors affecting the occurrence of precipitation can lead to a change in its amount. The atmospheric moisture is one of the most important factors for precipitation formation. In this study, changes in atmospheric moisture and its relation with occurrence of seasonal wet and dry periods were investigated in Iran. The re-analysis data from the ERA interim European ...

Sap flow in Bornean heath and dipterocarp forest trees during wet and dry periods.

Daytime xylem sap flow was measured by the compensation heat pulse velocity technique in dipterocarp forest trees growing on sandy loam (haplic acrisol) and in heath forest trees growing on bleached sand (albic arenosol) in Brunei during wet and dry periods. In dipterocarp forest trees, daily sap flow was stable during the dry period but declined on rainy days presumably as a result of reduced ...

Monitoring wet and dry process using precipitation changes

Urmia Lake desiccation and the signs of local climate changes

The water crisis is one of the important issues in the Middle East countries. Many lakes are ‎drying up and/or facing critical situations, exerting tremendous impacts on the socio-economics ‎of their region. Lake Urmia, in northwestern Iran, currently is facing critical situations and is on ‎the brink of total ‎shrinkage and environmental disaster. This paper investigates the roots of crises ‎t...

Spatial and Temporal Displacements in Wet and Dry Periods in the Southeast of the Caspian Sea: Golestan Province in Iran

The global warming phenomenon has had a great impact not only on the temperature patterns of the regions, but also on the spatial-temporal patterns of the occurrence of wet and dry days. As some areas have increased (decreased) the number of dry days, the result of these changes requires new approaches to water management in these areas. Golestan province in northern Iran is one of the province...
