Maximum value of daily maximum temperature

Let TX_x be the daily maximum temperatures in month k, period j. The maximum daily maximum temperature each month is then TX_xkj = max(TX_xkj).

Trends are calculated using a modified Theil-Sen Slope with significance calculated at the 5% level using a Mann-Kendall test shown with stippling for significant grid boxes. 70% of data must be present for a trend and significance to be calculated.

Time series are created as the weighted average of available grid boxes for each year. The dashed line represents a fitted 21-term Gaussian filter with padding at the start and end of the time series. Note: This means available grid boxes are not static with time. Averages are calculated for grid boxes with >70% of complete data for the index.

Minimum value of daily minimum temperature

Let TN_n be the daily minimum temperatures in month k, period j. The minimum daily minimum temperature each month is then TN_nkj=min(TN_nkj)

Maximum 1-day precipitation

Let RR_ij be the daily precipitation amount on day i in period j. The maximum 1-day value for period j are Rx1day_j = max (RR_ij)

Trends are calculated using a modified Theil-Sen Slope with significance calculated at the 5% level using a Mann-Kendall test shown with stippling for significant grid boxes. 70% of data must be present for a trend and significance to be calculated.

Annual total precipitation on wet days

Let RR_ij be the daily precipitation amount on day i in period j, then:
