Southwest Pacific Tropical Cyclone Outlook: Strong El Niño expected to produce above average activity and severe tropical storm impacts

Meteorological and climate analysis centres across the Southwest Pacific are indicating above average numbers of tropical cyclones (TC) for the 2015–16 season (November 2015 to April 2016). The 30-year average number of all Southwest Pacific tropical storms that formed between 1981-2010 is 12.4 for the November and April TC season. The average number of storms that developed into named TCs ...

Micro Pulse LiDAR: Perfect Tool for Atmospheric Research

Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the sensor provides a ...

Towards better utilization of NEXRAD data in hydrology: an overview of Hydro-NEXRAD

With a very modest investment in computer hardware and the open-source local data manager (LDM) software from University Corporation for Atmospheric Research (UCAR) Unidata Program Center, a researcher can receive a variety of NEXRAD Level III rainfall products and the unprocessed Level II data in real-time from most NEXRAD radars in the USA. Alternatively, one can receive such data from the ...

Evaluation of downscaled daily rainfall hindcasts over Sydney, Australia using statistical and dynamical downscaling approaches

The assessment of local and regional impacts of climate change often requires downscaling of general circulation model (GCM) projections from coarser GCM-scale to finer local- or catchment-scale spatial resolution. This paper provides an assessment of two downscaling approaches for simulation of daily rainfall over Sydney, Australia. The two downscaling alternatives compared include a ...

The Geoengineering Dilemma: To Speak or not to Speak

An intriguing dichotomy has developed within the field of atmospheric and climate research. On the one side, it has become common practice to examine pessimistic future scenarios of anthropogenic pollutant emissions and their environmental impacts. Not surprisingly, compared to the alternative “best guess” or “maximum feasible reduction” emissions scenarios, the pessimistic scenario simulations ...

Soil-surface CO2 fluxes in a Deyeuxia angustifolia wetland in Sanjiang Plain, China

In many temperate-zone ecosystems, seasonal changes in environmental and biological factors influence the dynamics and magnitude of surface–atmosphere exchange. Research was conducted between July and October 2001 to measure growing season surface-layer fluxes of CO2 in a Deyeuxia angustifolia dominated wetland on the Sanjiang Plain in northeastern China. Seasonal fluctuation and daily change in ...

Precipitation downscaling in climate modelling using a spatial dependence function

Climate change impacts are among the future significant effects on the socioeconomic, cultural and political affairs of any society, whether as towns, cities, regions, countries and the world at large. It is therefore necessary to predict future impacts by modelling logical and rational scenarios. Such scenarios are available internationally in the Special Report on Emission Scenarios (IPCC) and ...

Analysing online shopping attributes to influence consumer purchasing for fashion products

The fashion industry has stepped into the digital era. There are a great number of firms moving to be the digital companies with the major business process all being supported by the internet (Hajji et al., 2012; Bruce and Daly, 2011). A recent study from Mintel (2012) finds that online fashion purchase has increased by 152% in the UK over the last five years. The aim of this study is to ...

Bibliometric analysis of aerosol research in meteorology and atmospheric sciences

A bibliometric method was developed to investigate the aerosol research based on the papers from 1991 to 2009 in Science Citation Index Expanded, the Thomson Reuters. The analysed aspects covered scientific output and citation tracking on the basis of journal patterns; country; institute and author research performances. Improved indicators Peak–Year Citation per Publication and Relative ...

Influence of sea-land breezes on the tempospatial distribution of atmospheric aerosols over coastal region

The influence of sea-land breezes (SLBs) on the spatial distribution and temporal variation of particulate matter (PM) in the atmosphere was investigated over coastal Taiwan. PM was simultaneously sampled at inland and offshore locations during three intensive sampling periods. The intensive PM sampling protocol was continuously conducted over a 48-hr period. During this time, PM2.5 and ...

Drops in a Cloud: An SBIR-funded spectrometer is at the forefront of global climate research

Weeks before the athletes took to the ice and snow at the 2018 Winter Olympics in South Korea, Dr. Duncan Axisa was in the mountains around PyeongChang, studying ice-forming particles. Later in the year, Axisa traveled to India to study monsoon clouds, and to France to participate in a trans-national ice-nucleation experiment. Axisa and his team travel around the globe to help scientists better ...

Remotely sensed seasonal dynamics of phytoplankton in the Ligurian Sea in 1997–1999

Remotely sensed data and a one-dimensional hydrophysical model were used to study the seasonal dynamics of surface plant pigments concentration in the Ligurian-Provençal basin. The variations of phytoplankton biomass were estimated from the observations of the Coastal Zone Color Scanner (1978–1986) and Sea-viewing Wide Field-of-view Sensor (SeaWiFS) (September 1997 to October ...
