PORTw: Annual Maximum and Minimum Temperature

In extRemes: Extreme Value Analysis

Annual Maximum and Minimum Temperature

Description

Annual maximum and minimum Winter temperature (degrees centigrade) with a covariate for the North Atlantic Oscillation index from 1927 through 1995. Data is for Winter for Port Jervis, New York (PORTw) and Spring for Sept-Iles, Quebec (SEPTsp).

Usage

data(PORTw)

Format

A data frame with 68 observations on the following 16 variables.

Year

a numeric vector giving the year.

MTMAX

a numeric vector giving the mean winter maximum temperatures (degrees centigrade).

MTMIN

a numeric vector giving the mean winter minimum temperatures (degrees centigrade).

STDTMAX

a numeric vector giving the standard deviations of maximum winter temperatures (degrees centigrade).

STDMIN

a numeric vector giving the standard deviations of minimum winter temperatures (degrees centigrade).

TMX1

a numeric vector giving the maximum winter temperature (degrees centigrade).

TMN0

a numeric vector giving the minimum winter temperature (degrees centigrade).

MDTR

a numeric vector giving the mean winter diurnal temperature range (degrees centigrade).

AOindex

a numeric vector giving the Atlantic Oscillation index (see Thompson and Wallace (1998)).

Details

See Wettstein and Mearns (2002) for a much more detailed explanation of the above variables.
