US Climate Division Dataset Seasonal Correlation Page
Note: There has been a major dataset version update. This page is using the newer dataset

Plot correlations of US climate division data with atmospheric/ocean time-series (supplied) or custom time-series.

Choose the variable, index time-series and year range desired. A map of the correlation of that variable with the index for the season chosen will be plotted. Data is taken from the National Climatic Data Center's climate division dataset. The full dataseet covers to Jan 2018 . Most index timeseries do not cover the whole time period.

  1. Which variable?
  2. Beginning month of season Ending month
  3. Monthly or Seasonal Values Seasonal Average Monthly Values
  4. Enter start and end years for correlations (e.g. 1972) (for seasons that span a year (e.g. DJF), please enter year of the LAST month).
    Default is 1948-2011.
  5. Time Series? If custom:
  6. (Optional) Enter months or seasons index time series leads or lags correlating variable.
  7. (Optional) Set Contour Interval/Range Low: Hi: Contour Interval:
    For this option, you must input all 3 input values There is a limit of 32 intervals.
