Comments on "Assessing future risk: quantifying the effects of sea level rise on storm surge risk for the southern shores of Long Island, New York," by Christine C. Shepard, et al (Natural Hazards, Vol. 60, No. 2, 727-745)
Comments Assessing future risk effects of sea level rise the southern shores of Long Island
2012/4/19
Tide gauge and satellite data indicate that the rate of sea level rise has not increased significantly in response to the last 3/4 century of CO2 emissions, so there is no reason to expect that it wil...
On the effects of clouds and hazes in the atmospheres of hot Jupiters: semi-analytical temperature-pressure profiles
planets and satellites:atmospheres – radiative transfer
2011/8/16
Abstract: Motivated by the work of Guillot (2010), we present a semi-analytical formalism for calculating the temperature-pressure profiles in hot Jovian atmospheres which includes the effects of clou...
A sensitivity study on the effects of particle chemistry, asphericity and size on the mass extinction efficiency of mineral dust in the earth's atmosphere: from the near to thermal IR
particle chemistry asphericity size mineral dust the earth's atmosphere thermal IR
2011/2/25
To determine a plausible range of mass extinction efficiencies (MEE) of terrestrial atmospheric dust from the near to thermal IR, sensitivity analyses are performed over an extended range of dust micr...
Effects of absorbing aerosols in cloudy skies: a satellite study over the Atlantic Ocean
aerosols cloudy skies a satellite study the Atlantic Ocean
2011/2/25
We present a method for deriving the radiative effects of absorbing aerosols in cloudy scenes from satellite retrievals only. We use data of 2005–2007 from various passive sensors aboard satellites of...
Soot microphysical effects on liquid clouds, a multi-model investigation
carbonaceous aerosols liquid clouds a multi-model investigation
2011/2/25
We use global models to explore the microphysical effects of carbonaceous aerosols on liquid clouds. Although absorption of solar radiation by soot warms the atmosphere, soot may cause climate cooling...
Aerosol effects on ice clouds: can the traditional concept of aerosol indirect effects be applied to aerosol-cloud interactions in cirrus clouds?
Aerosol effects ice clouds aerosol indirect effects aerosol-cloud interactions cirrus clouds
2010/11/29
Cirrus clouds cover approximately 20–25% of the globe and thus play an important role in the Earth's radiation budget. Therefore the effect of aerosols on cirrus clouds can have a substantial impact o...
Extreme events in total ozone over Arosa – Part 2: Fingerprints of atmospheric dynamics and chemistry and effects on mean values and long-term changes
Extreme events total ozone Arosa atmospheric dynamics and chemistry and effects mean values long-term changes
2010/11/3
In this study the frequency of days with extreme low (termed ELOs) and extreme high (termed EHOs) total ozone values and their influence on mean values and trends are analyzed for the world's longest ...
Sub-10 nm particle growth by vapor condensation – effects of vapor molecule size and particle thermal speed
Sub-10 nm particle vapor condensation vapor molecule size particle thermal speed
2010/10/21
The growth of freshly formed nanoparticles has been investigated. A new analytical expression based on a recently developed exact solution for the condensational growth rate has been derived. Based on...
Black carbon semi-direct effects on cloud cover: review and synthesis
Black carbon semi-direct effects cloud cover
2010/8/25
Absorbing aerosols (AAs) such as black carbon (BC) or dust absorb incoming solar radiation, perturb the temperature structure of the atmosphere, and influence cloud cover. Previous studies have descri...
A global modeling study on carbonaceous aerosol microphysical characteristics and radiative effects
carbonaceous aerosol microphysical characteristics radiative effects
2010/8/16
Our best estimate for net direct and indirect aerosol radiative flux change between 1750 and 2000 is −0.56 W/m2. However, the direct and indirect aerosol effects are quite sensitive to the black...

meteorological factors fire activity the North American boreal forest fire weather forecasting
2010/8/16
The effects of lightning and other meteorological factors on wildfire activity in the North American boreal forest are statistically analyzed during the fire seasons of 2000–2006 through an integratio...
Trends in long-term gaseous mercury observations in the Arctic and effects of temperature and other atmospheric conditions
long-term gaseous mercury observations the Arctic temperature and other atmospheric conditions
2010/8/13
Gaseous elemental mercury (GEM) measurements at Alert, Canada, from 1995 to 2007 were analyzed for statistical time trends and for correlations with meteorological and climate data. A significant decr...
Effects of relative humidity on aerosol light scattering in the Arctic
relative humidity aerosol light the Arctic
2010/8/12
Aerosol particles experience hygroscopic growth in the ambient atmosphere. Their optical properties – especially the aerosol light scattering – are therefore strongly dependent on the ambient relative...
