SANTOS, Carlos Antonio Costa dos; RAO, Tantravahi Venkata Ramana  e  OLINDA, Ricardo Alves de. Trends in temperature and growing season length in idaho-usa during the past few decades. Rev. bras. meteorol. [online]. 2015, vol.30, n.4, pp.359-370. ISSN 0102-7786.  https://doi.org/10.1590/0102-778620130002.

This study attempts to provide new information on seasonal and annual trends, on a regional scale, using records of daily air temperature over Idaho, USA, through the analysis of the Growing Season Length (GSL), and maximum and minimum air temperature data from multiple stations in the region, as well as, to obtain the temporal correlation between the daily air temperature and Sea Surface Temperature (SST) indices. The analyses were conducted using long-term and high quality data sets for 35 meteorological stations for the period between 1970 and 2006. The results suggest that both daily maximum and minimum temperatures had increasing trends, but the minimum air temperature is increasing faster than the maximum air temperature. On average, the GSL has increased by 7.5 days/decade during the period 1970-2006, associated with increasing temperatures. Trends in regional air temperature and their indication of climate change are of interest to Idaho and the rest of the world. The trends obtained herein corroborate with the general idea that during the last century the globe has warmed.
