rain.feedback.stats: Statistics of rain feedback in Australia

In FeedbackTS: Analysis of Feedback in Time Series

Description

Feedback and change-in-feedback statistics based on 88 rainfall data series colllected in 88 sites across Australia.

Usage

data(rain.feedback.stats)

Format

A data frame with 88 observations on the following 8 variables.

Station.number:

a numeric vector providing the identifiers of the meteorological stations.

Keyday.threshold:

a numeric vector providing for each meteorological station the threshold value above which a day is considered as a key day.

Longitude:

a numeric vector with longitudes of the meteorological stations.

Latitude:

a numeric vector with latitudes of the meteorological stations.

Feedback.whole.period:

a numeric vector providing for each meteorological station the temporal average of after-before differences around key days calculated from the whole time series.

Feedback.before.1960:

a numeric vector providing for each meteorological station the temporal average of after-before differences around key days calculated from the time series right-truncated in 1960 (data from year 1960 were excluded).

Feedback.after.or.in.1960:

a numeric vector providing for each meteorological station the temporal average of after-before differences around key days calculated from the time series left-truncated in 1960 (data from year 1960 were kept).

Change.in.feedback:

a numeric vector providing the difference between Feedback.after.or.in.1960 and Feedback.before.1960.

Details

The statistics in this data set were computed using the feedback.stats function.

Examples

#### load data of feedback and change-in-feedback indices in 88 sites across Australia
data(rain.feedback.stats)

#### spatial coordinates of the 88 sites and corresponding feedback index 
#### computed from the whole data series
coord=rain.feedback.stats[,3:4]
stat1=rain.feedback.stats[["Feedback.whole.period"]]

#### map of feedback index 
map.statistic(coord,stat1,cex.circles=c(3,0.2),
   region=list(border="Australia",xlim=c(110,155)),
   legend=list(x=c(rep(114,3),rep(123,2)),y=-c(37,39.5,42,37,39.5),
      xtext=c(rep(114,3),rep(123,2))+1,ytext=-c(37,39.5,42,37,39.5),digits=2),
