Observed Decrease in Soil and Atmosphere Temperature Coupling in Recent Decades Over Northern Eurasia

The Analysis of Monthly moisture advection changes in Iran’s atmosphere over the recent half-century

Probabilistic projections of 21st century climate change over Northern Eurasia

We present probabilistic projections of 21st century climate change over Northern Eurasia using the Massachusetts Institute of Technology (MIT) Integrated Global System Model (IGSM), an integrated assessment model that couples an Earth system model of intermediate complexity with a two-dimensional zonal-mean atmosphere to a human activity model. Regional climate change is obtained by two downsc...

The role of soil ice in land‐atmosphere coupling over the United States: A soil moisture–precipitation winter feedback mechanism

[1] We perform two 23 year simulations using a regional climate model coupled with the National Center for Atmospheric Research Community Land Model version 3.5 (RegCM‐CLM) to investigate land‐atmosphere coupling in the continental United States during the cold season (October–April) and the role of soil water phase. One simulation allows the land surface to interact freely (RunI) while the oth...

Spatial Analysis of variation of inter-annual distribution of precipitation in Iran over recent decades (1970-2016)

Introduction Geographical situation of Iran is a place for interacting many physical and human processes which lead to specific precipitation climatology in the country. The month to month variation of precipitation is one of  the features which the precipitation climatology may reflect due to tempo - spatial characteristics. In fact, monthly distribution of precipitation is one of precipitati...

Change in snow phenology and its potential feedback to temperature in the Northern Hemisphere over the last three decades

Trends in the duration or extent of snow cover are expected to feedback to temperature trends. We analyzed trends in dates of onset and termination of snow cover in relation to temperature over the past 27 years (1980–2006) from over 636 meteorological stations in the Northern Hemisphere. Different trends in snow duration are observed over North America and Eurasia. Over North America, the term...
