Abrupt change in climate and climate models

First, we review the evidence that abrupt climate changes have occurred in the past and then demonstrate that climate models have developing capacity to simulate many of these changes. In particular, the processes by which changes in the ocean circulation drive abrupt changes appear to be captured by climate models to a degree that is encouraging. The evidence that past changes in the ocean hav...

Forecasting the effects of climate change on the climatic of the Miahne-city using climate models (SDSM)

The purpose of this study is to determine and predict the effects of climate change on architecture using climate models. By clarifying the consequences of the impact of urban architecture on climate change while using the data of surrounding stations with library and field data methods. The climatic parameters of precipitation, temperature and relative humidity of the synoptic station of Miyan...

Estimating the Growing Degree Days in the Northwest of Iran based on Climate Change Models

The purpose of this study is predicting climate changes and investigating the effect of probable climate change on the growing degree-days in the northwest of Iran. For this purpose the climatic data of seven synoptic stations during a 25 years period (1985-2009) was collected including Oroomieh, Tabriz, Zanjan, Sanandaj, Ghazvin, Kermanshah, and Hamedan were used as the base period and thus te...

Climate change and occupational heat problems.

In many parts of the world ongoing climate change during the last three decades has produced higher temperatures and occupational heat stress levels in both outdoor and indoor workplaces 1, 2). Working people are particularly exposed to these heating trends in tropical and subtropical countries, where excessive workplace heat exposures linked to the outdoor ambient thermal environment are a tra...
