This paper investigates the magnitude and causes of spatial variability surface radiative fluxes in a complex alpine landscape Southern Alps New Zealand. Radiative flux components are simulated for Tekapo watershed at 100-m resolution clear-sky summer days, using radiation budget model conjunction with satellite imagery topographic modeling to derive parameters. Overall, results agree well observations made range sites, shortwave more accurately than longwave fluxes. Sensitivity studies were...
Abstract. Modification of the intensity a low level jet (LLJ) and near-surface wind speed by mineral dust is important as it has implications for emission its long-range transport. Using Weather Research Forecasting with Chemistry (WRF/Chem) regional model, shown that direct radiative forcing reduces temperature in lower atmosphere, but increases layers aloft. The surface cooling to be associated reduction turbulent kinetic energy (TKE) hence vertical mixing horizontal momentum. Changes...
Grapevine phenology is advancing with increased temperatures associated climate change. This may result in higher fruit sugar concentrations at harvest and/or earlier compressed harvests and changes the synchrony of other metabolites. One adaptation strategy that growers use to maintain typicity wine style change cultivars. approach enable develop under temperature conditions similar those typically style. We demonstrate Flowering Véraison (GFV) Sugar Ripeness (GSR) models can be implemented...
The Southern Alps Experiment is being mounted to study the influence of New Zealand's on local weather and climate. This paper describes these alpine influences outlines proposed field modeling experiments. goals include understanding quantifying factors that govern intensity spatial distribution heavy rainfall, west east precipitation across mountains, lee wind storms warming. Linked research will explore use deterministic rainfall models predict river flows from mountain watersheds.
A kinematic trajectory model is used to investigate potential pathways of dust transport from Australia New Zealand. Historically, these have been assumed follow rather direct west–east trajectories spanning 2 3 days, often resulting in red snow events the Southern Alps However, results present study which examined route taken by air parcels originating southern during storms on 24 and 25 May 1994, indicate that trans-Tasman are more diverse than previously thought, display considerable...
A growing body of evidence supports an association between air pollution exposure and adverse mental health outcomes, especially in adulthood however, very little is known about the effects early life during childhood. We examined longitudinal associations extent timing children's annual from conception to age 10 years a wide range cognitive, educational outcomes childhood adolescence that were assessed prospectively as part large birth cohort study. linked historical data (μg.m-3) pregnancy...
Abstract Heat balance observations were carried out during fine conditions at a site on the lower Franz Josef Glacier in June 1988 and February 1990 compared with results obtained August, October, December 1981. Surface ice melt occurred all seasons, mean rate summer about eight times larger than winter. The seasonal variation of various contributions to was also identified. Sensible heat flux dominant source, contributing 80 per cent 55 total energy gain winter summer, respectively. Latent...
Spring frost events pose a significant risk to viticulture (Poni S. et al., 2022). In Marlborough, New Zealand's leading wine region, the economy is heavily dependent on vineyard yields, making spring very important threat consider. This exacerbated in context of climate change, as increase warmer temperatures has led advancement phenological stages grapevines, notably bud break (Van Leeuwen C., 2016). This makes grapevines more vulnerable frost, new growth then exposed potential...
Abstract In Christchurch and other Canterbury towns on the east coast of New Zealand's South Island, poor dispersion conditions high emissions particulate matter carbon monoxide regularly lead to build‐up smog during anticyclonic weather in wintertime. This study analyses surface wind fields nights using data collected Air Pollution Study 2000 (CAPS2000). Westerly land breezes drainage winds from foothills Southern Alps Plains are evident all coastal towns, but local terrain features often...
Coral reefs are thought to face significant threat from global warming due increased water temperatures and ocean acidity. However, research into the surface energy balance of coral their associated micrometeorology is rare. Here we present, through a case study approach, first direct in situ measurements Heron Reef, small platform reef southern Great Barrier Australia. Surface exchanges were measured using eddy covariance method show that during winter spring an estimated 80–98% net...
ABSTRACT This paper contributes to knowledge of the impact global warming on viticulture, using major vineyard regions New Zealand as a case study illustrate regional disparities in climate change impacts resulting from downscale effects larger scale atmospheric circulation. Recent trends air temperature areas are investigated. Trends since 1941 Marlborough show an increase range, with both rising maximum temperatures and declining minimum temperatures, but no annual mean. More hot days...
