- Another year has passed, and indeed it has been turbulent for many of us. Despite the hardship in many aspects of life, our Associated Editors have made tremendous effort and thus, Geografiska Annaler: Series A, Physical Geography have successfully published volume 102 with 4 issues, including a special issue on different aspects of dendrochronology in Asia.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- With this first issue of volume 99 of Geografiska Annaler, Series A: Physical Geography, the journal has undergone several changes. First of all, we are pleased to now collaborate with Taylor & Francis. This move will not affect how authors interact with the journal, but we see this as part of the continuous improvement of it. Also, we have changed to a new layout which better caters for online reading than the two-column format the journal has used since 1965. With this change in style we have also implemented a new reference format, which follows the Council of Science Editors (CSE) style. This is a form which is simple and concise, and also easily available in different writing tools that can aid the author

Tidskriftsartikel (refereegranskat)abstract
- To make predictions of future climate it is necessary to understand the past climate-temperature as well as precipitation. While a wealth of temperature proxies exist from northern latitudes, there is still a lack of information about past precipitation variability. Here we present a 300-year-long tree-ring width chronology from xeric-site Scots pines (Pinus sylvestris L.) in Tyresta National Park, east central Sweden. Tree-ring widths were compared to the long observed temperature and precipitation records from Stockholm during 1786-2000. Analyses of the climate/growth relationship showed that, in general, May-June precipitation had a dominating influence on pine growth. However, during dry periods, negative responses to June-July temperature were stronger, especially evident in the late nineteenth century. Periods of below-average growth were associated with dry conditions in May-June, but occasionally periods of wet and cool summers also produced narrow rings. Periods of above-average growth were linked to wet, but sporadically also cool and dry, early summers. The years between 1815 and 1833 appear to be particularly dry in the 300-year context. Since growth anomalies are found in other Swedish drought-sensitive tree-ring chronologies during this period, it is likely that this dry period had a regional extent. This is the first tree-ring chronology from southern Sweden that provides multi-century information of past summer drought and moisture variability with high resolution and the study will add important information regarding past climate variability in southern Sweden.

Summer temperature variability in central Scandinavia during the last 3600 years

Ingår i: Geografiska Annaler Series a-Physical Geography. - 0435-3676. ; 87A:1, s. 231-241

Tidskriftsartikel (refereegranskat)abstract
- A Scots pine (Pinus sylvestris L.) treering width chronology from Jamtland, in the central Scandinavian Mountains, built from living and sub-fossil wood, covering the period 1632 BC to AD 2002, with a minor gap during AD 887-907, is presented. This is the first multi-millennial tree-ring chronology from the central parts of Fennoscandia. Pine growth in this tree line environment is mainly limited by summer temperatures, and hence the record can be viewed as a temperature proxy. Using the regional curve standardization (RCS) technique, pine-growth variability on short and long time scales was retained and subsequently summer (June-August) temperatures were reconstructed yielding information on temperature variability during the last 3600 years. Several periods with anomalously warm or cold summers were found: 450-550 BC (warm), AD 300-400 (cold), AD 900-1000 (the Medieval Warm Period, warm) and AD 1550-1900 (Little Ice Age, cold). The coldest period was encountered in the fourth century AD and the warmest period 450 to 550 BC. However, the magnitude of these anomalies is uncertain since the replication of trees in the Jamtland record is low during those periods. The twentieth century warming does not stand out as an anomalous feature in the last 3600 years. Two multi-millennial tree-ring chronologies from Swedish and Finnish Lapland, which have previously been used as summer temperature proxies, agree well with the Jamtland record, indicating that the latter is a good proxy of local, but also regional, summer temperature variability.
