Humidity determines snowpack ablation under a warming climate

  
Proceedings of the National Academy of Sciences, Vol. 115, No. 6. (06 January 2018), pp. 1215-1220, https://doi.org/10.1073/pnas.1716789115

Abstract

[Significance] Changes in the amount and timing of snowmelt have large effects on water for society and ecosystems. Using long-term records from across the western United States, we demonstrate that atmospheric humidity is a major control on how seasonal snow responds to warming temperatures. Specifically, we observe an increase in the frequency and magnitude of episodic winter melt events under higher humidity that may alter the timing of water availability. In lower-humidity regions, however, warming is associated with increased sublimation and/or evaporation ...

 

cffdrs: an R package for the Canadian Forest Fire Danger Rating System

  
Ecological Processes, Vol. 6, No. 1. (31 January 2017), 5, https://doi.org/10.1186/s13717-017-0070-z

Abstract

[Introduction] The Canadian Forest Fire Danger Rating System (CFFDRS) is a globally known wildland fire risk assessment system, and two major components, the fire weather index system and the fire behavior prediction system, have been extensively used both nationally and internationally to aid operational wildland fire decision making. [Methods] In this paper, we present an overview of an R package cffdrs, which is developed to calculate components of the CFFDRS, and highlight some of its functionality. In particular, we demonstrate how these functions could ...

Abstract

Forests cover over a third of the total land area of Europe. In recent years, large forest fires have repeatedly affected Europe, in particular the Mediterranean countries. Fire danger is influenced by weather in the short term, and by climate when considering longer time intervals. In this work, the emphasis is on the direct influence on fire danger of weather and climate. [\n] For climate analysis at the continental scale, a daily high-emission scenario (RCP 8.5) was considered up to the end ...

Global risk of deadly heat

  
Nature Climate Change, Vol. 7, No. 7. (19 June 2017), pp. 501-506, https://doi.org/10.1038/nclimate3322

Abstract

Climate change can increase the risk of conditions that exceed human thermoregulatory capacity. Although numerous studies report increased mortality associated with extreme heat events, quantifying the global risk of heat-related mortality remains challenging due to a lack of comparable data on heat-related deaths. Here we conducted a global analysis of documented lethal heat events to identify the climatic conditions associated with human death and then quantified the current and projected occurrence of such deadly climatic conditions worldwide. We reviewed papers published ...

 

Simultaneous estimation of daily solar radiation and humidity from observed temperature and precipitation: an application over complex terrain in Austria

  
Agricultural and Forest Meteorology, Vol. 104, No. 4. (15 September 2000), pp. 255-271, https://doi.org/10.1016/s0168-1923(00)00170-2

Abstract

Using daily observations of temperature, precipitation, radiation, and humidity from 24 stations spanning a large elevation gradient in Austria, we tested several previously defined algorithms for estimating daily radiation and humidity. The estimation algorithms were first tested independently, and then combined, resulting in a combined algorithm for estimating both radiation and humidity that relies only on temperature and precipitation inputs. Mean absolute errors (MAE) for joint radiation and humidity estimates were 2.52 MJ m −2 per day and 85.6 Pa, respectively, close to values ...

 

The National Fire-Danger Rating System: basic equations

  
Vol. PSW-82 (1985)

Abstract

Updating the National Fire-Danger Rating System (NFDRS) was completed in 1977, and operational use of it was begun the next year. The System provides a guide to wildfire control and suppression by its indexes that measure the relative potential of initiating fires. Such fires do not behave erratically–they spread without spotting through continuous ground fuels. Estimates of fire potential have a basis in the mathematical models used for fire behavior. The fire manager must select the fuel model that best represents ...

 

Meteorological aspects of forest fire danger rating

  
Journal of the South African Forestry Association, Vol. 29, No. 1. (1 January 1957), pp. 31-38, https://doi.org/10.1080/03759873.1957.9630816

Abstract

The effect of past weather conditions on inflammability and the influence of weather on fire behaviour are discussed. Using a method of deriving inflammability from rainfall, temperature and humidity data the frequency of days of high inflammability in January, February and March in the Cape over eight years is derived and shows a maximum in mid-February. With the use of a burning index meter daily values of fire danger rating at the Cape for the same months in 1953–1955 are derived. ...

 

Discussing the role of tropical and subtropical moisture sources in cold season extreme precipitation events in the Mediterranean region from a climate change perspective

  
Natural Hazards and Earth System Sciences, Vol. 16, No. 1. (27 January 2016), pp. 269-285, https://doi.org/10.5194/nhess-16-269-2016

Abstract

This paper presents a review of a large number of research studies performed during the last few decades that focused on the investigation of cold season extreme precipitation events (EPEs) in the Mediterranean region (MR). The publications demonstrate the important role of anomalously intense transports of moist air from the tropical and subtropical Atlantic in the occurrence of EPEs in the MR. EPEs in the MR are directly or indirectly connected to narrow bands with a high concentration of moisture in ...

 

A study of the relation of meteorological variables to monthly provincial area burned by wildfire in Canada (1953-80)

  
Journal of Applied Meteorology and Climatology, Vol. 27, No. 4. (1 April 1988), pp. 441-452, https://doi.org/10.1175/1520-0450(1988)027<0441:asotro>2.0.co;2

Abstract

The relation between meteorological variables and the monthly area burned by wildfire from May to August 1953–80 in nine Canadian “provinces” was investigated. A purely statistical approach to estimating the monthly provincial area burned, using meteorological variables as predictors, succeeded in explaining 30% of the variance west of Lake Nipigon and about 11% east of Lake Nipigon. [\n] Long sequences of days with less than 1.5 mm of rain or days with relative humidities less than 60% proved to have the highest ...

 

Increasing daily wildfire risk in the Acadian Forest Region of Nova Scotia, Canada, under future climate change

  
Regional Environmental Change, Vol. 15, No. 7. (2015), pp. 1447-1459, https://doi.org/10.1007/s10113-014-0698-5

Abstract

A conceptual system dynamic model of the impact of future climate change on fire risk in the Nova Scotian Acadian Forest Region (NS AFR) was developed, clarifying the influence of positive and negative drivers of future fire risk. Weights of relative importance for seven wildfire risk drivers identified in the conceptual model were elicited through an analytical hierarchy process. Expert participants identified precipitation, temperature, and local tree species composition as the most important determinants of future fire risk. Fire weather variables ...

 

Plant responses to increasing CO2 reduce estimates of climate impacts on drought severity

  
Proceedings of the National Academy of Sciences, Vol. 113, No. 36. (06 September 2016), pp. 10019-10024, https://doi.org/10.1073/pnas.1604581113

Abstract

[Significance] We show that the water savings that plants experience under high CO2 conditions compensate for much of the effect of warmer temperatures, keeping the amount of water on land, on average, higher than we would predict with common drought metrics, and with a different spatial pattern. The implications of plants needing less water under high CO2 reaches beyond drought prediction to the assessment of climate change impacts on agriculture, water resources, wildfire risk, and vegetation dynamics. [Abstract] Rising atmospheric CO2 will make Earth ...

Climatic impact of global-scale deforestation: radiative versus nonradiative processes

  
Journal of Climate, Vol. 23, No. 1. (1 January 2010), pp. 97-112, https://doi.org/10.1175/2009jcli3102.1

Abstract

A fully coupled land-ocean-atmosphere GCM is used to explore the biogeophysical impact of large-scale deforestation on surface climate. By analyzing the model sensitivity to global-scale replacement of forests by grassland, it is shown that the surface albedo increase owing to deforestation has a cooling effect of -1.36 K globally. On the other hand, forest removal decreases evapotranspiration efficiency and decreases surface roughness, both leading to a global surface warming of 0.24 and 0.29 K, respectively. The net biogeophysical impact of deforestation ...

 

Complex climate controls on 20th century oak growth in Central-West Germany

  
Tree Physiology, Vol. 29, No. 1. (01 January 2009), pp. 39-51, https://doi.org/10.1093/treephys/tpn003

Abstract

We analyze interannual to multi-decadal growth variations of 555 oak trees from Central-West Germany. A network of 13 pedunculate oak (Quercus robur L.) and 33 sessile oak (Quercus petraea (Matt.) Liebl.) site chronologies is compared with gridded temperature, precipitation, cloud-cover, vapor pressure and drought (i.e., Palmer Drought Severity Index, PDSI) fluctuations. A hierarchic cluster analysis identifies three groups for each oak species differentiated by ecologic settings. When high precipitation is primarily a characteristic for one Q. robur and one Q. petraea ...

 

Emergent relation between surface vapor conductance and relative humidity profiles yields evaporation rates from weather data

  
Proceedings of the National Academy of Sciences, Vol. 110, No. 16. (16 April 2013), pp. 6287-6291, https://doi.org/10.1073/pnas.1215844110

Abstract

The ability to predict terrestrial evapotranspiration (E) is limited by the complexity of rate-limiting pathways as water moves through the soil, vegetation (roots, xylem, stomata), canopy air space, and the atmospheric boundary layer. The impossibility of specifying the numerous parameters required to model this process in full spatial detail has necessitated spatially upscaled models that depend on effective parameters such as the surface vapor conductance (Csurf). Csurf accounts for the biophysical and hydrological effects on diffusion through the soil and vegetation ...
