Climate Assessments

  • Identification and tracking of extra-tropical cyclones (ETC) in the CMIP5 simulations were carried out. Analysis of Northern Hemisphere ETCs in the CMIP5 models is focused on the future climate change of ETC frequency, intensity and duration.
  • A 6-hourly dataset of geopotential height on pressure levels was created using CMIP5 temperature, surface pressure, and topography data. This dataset covers the time period from 1950 to 2100, and is used for identification and tracking of blocking anticyclones.
  • Produced CMIP5 data with resolution of 5 km over the United States for analyses of climate change in each of the 50 states. Variables are surface temperature, precipitation, maximum and minimum daily temperature, maximum 1-day precipitation, and growing season length for four scenarios and historical simulations.
  • Temperature scaled by global temperature with different warming thresholds was carried out for the 50 states and 8 NCA regions in the United States using CMIP5 data.
Annual time series of the cold season (November – March) ETC occurrences in the Northern Hemisphere. The numbers of ETCs are multi-model means from 23 CMIP5 global climate simulations for the historical period (1950-2005), and under the RCP8.5 scenarios (2006-2100).
