Changes in seasonal patterns

open access: yesJournal of Economic Dynamics and Control, 1994
This paper explores the hypothesis that the seasonal patterns of macroeconomic variables vary with expansions and contractions. Graphical techniques and generalized predictive tests for structural stability are used to identify and test patterns of changing seasonality.

Seasonal deuterium excess in a Tien Shan ice core: Influence of moisture transport and recycling in Central Asia [PDF]

open access: yes, 2003
Stable water isotope (δ18O, δD) data from a high elevation (5100 masl) ice core recovered from the Tien Shan Mountains, Kyrgyzstan, display a seasonal cycle in deuterium excess (d = δD − 8*δ18O) related to changes in the regional hydrologic cycle during ...

Analysing seasonal changes in New Zealand's largest inbound market [PDF]

open access: yes, 2008
The purpose of the paper is to analyse seasonal changes in tourism demand by New Zealand's major tourist source market, Australia, for the period 1979-2005. A time series regression model is used to test the significance of monthly seasonality.

Changing seasonality of the Baltic Sea [PDF]

open access: yesBiogeosciences, 2015
Abstract. Changes in the phenology of physical and ecological variables associated with climate change are likely to have significant effect on many aspects of the Baltic ecosystems. We apply a set of phenological indicators to multiple environmental variables measured by satellite sensors for 17–35 years to detect possible changes in the seasonality ...

Average seasonal changes in chlorophyll a in Icelandic waters [PDF]

open access: yes, 2009
The standard algorithms used to derive sea surface chlorophyll a concentration from remotely sensed ocean colour data are based almost entirely on the measurements of surface water samples collected in open sea (case 1) waters which cover ~60% of the ...
