“…Their value for the present study stems from the fact that tree-rings can provide a long-term history of changes in the frequency and intensity of climate extremes. Therefore, tree-rings have been employed worldwide to study climate extremes, such as droughts (Liang et al, 2006;Stahle et al, 1998), hurricanes (Drew, 1998), and tropical cyclone activities (Miller et al, 2006;Rodgers et al, 2006).…”

“…This particular air mass approach has not been used in dendroclimate research. Rodgers et al (2006) found tree growth to be moderately related to seasonal precipitation and PDSI in this warm and moist climate. However, in this study, correlations with air mass variability were substantially higher.…”

“…Their results indicate that soil moisture and precipitation are positively correlated with tree growth during peak evaporation months (Meldahl et al 1999). In another study nearby, Rodgers et al (2006) showed the presence of tropical cyclone signatures within tree rings from eastern Mobile Bay. Tree rings within this coastal forest were also significantly correlated to summer (June-August) Palmer Drought Severity Index (PDSI) (Palmer 1965) values and summer precipitation (Rodgers et al 2006).…”

“…For example, on the eastern shore of Mobile Bay, seasonal mean climate division temperatures had no significant relationship with tree growth. Additionally, mean climate division annual precipitation and annual PDSI were only moderately correlated to tree growth (Rodgers et al 2006). Thus, the use of seasonal climate variables may be of limited utility when evaluating cumulative growth throughout the entire growing season.…”

This study investigates the relationship between tree growth and air mass type variability, using the spatial synoptic classification (SSC) in a bottomland slash pine forest in coastal Alabama (USA). The use of an air mass approach in dendroclimatology is somewhat unconventional and has not been fully explored. However, we believe that it may be useful because the air mass approach represents a holistic and comprehensive measure of surface conditions. Cores from 36 slash pines (Pinus elliotti) were extracted and ring widths were measured to the nearest 0.01 mm. The cores were then cross-dated and a standardized ring index series was established. Relationships were explored between the index series and several climate variables and teleconnections. The index series showed significant relationships with SSC air mass types and SSC air mass ratios, but insignificant results with teleconnections. Specifically the Dry Tropical air mass type was negatively correlated with tree growth while Moist Moderate was positively correlated. Concomitantly, Dry Tropical : Moist Moderate, Dry Tropical : Moist Tropical, and Dry Moderate : Moist Moderate air mass ratios also showed negative correlations. Positive Pacific Decadal Oscillation (PDO) sea surface temperatures were also associated with significant moisture and air mass variability in the region, although the PDO did not have a significant relationship with tree growth. The significance between SSC air mass variability and tree growth in the humid subtropical climate of coastal Alabama has favorable implications for dendroclimatological research in drier environments where trees are more sensitive to climatic variables.

Declining Radial Growth Response of Coastal Forests to Hurricanes and Nor'easters

et al. 2018

The Mid‐Atlantic coastal forests in Virginia are stressed by episodic disturbance from hurricanes and nor'easters. Using annual tree ring data, we adopt a dendroclimatic and statistical modeling approach to understand the response and resilience of a coastal pine forest to extreme storm events, over the past few decades. Results indicate that radial growth of trees in the study area is influenced by age, regional climate trends, and individual tree effects but dominated periodically by growth disturbance due to storms. We evaluated seven local extreme storm events to understand the effect of nor'easters and hurricanes on radial growth. A general decline in radial growth was observed in the year of the extreme storm and 3 years following it, after which the radial growth started recovering. The decline in radial growth showed a statistically significant correlation with the magnitude of the extreme storm (storm surge height and wind speed). This study contributes to understanding declining tree growth response and resilience of coastal forests to past disturbances. Given the potential increase in hurricanes and storm surge severity in the region, this can help predict vegetation response patterns to similar disturbances in the future.
