“…A main requirement for the appearance of the publicly available drought map is intelligibility. For the visualization of drought events, we adapted the appearance of the GDM to that of the US Drought Monitor (Svoboda et al 2002), using five classes. Four classes define drought conditions, and the fifth class describes the pre-warning state of abnormally dry (table 1).…”

“…Drought has widespread influence over the continental United States (Svoboda et al 2002). For example, in 2011, there was an extensive drought extending almost continuously across the southern United States from Arizona to North Carolina (NCDC 2014).…”

“…In the most influenced region in Texas, annual precipitation dropped by more than 50% from 667 mm (1895-2011 climatology) to 267 mm for the 2011 water year (October 2010-September 2011) (Long et al 2013). The composite drought severity index (Svoboda et al 2002) provided by the U.S. Drought Monitor (www.droughtmonitor.unl.edu) shows that until late June 2011, more than 88% areas in the southern and 84% in the southeastern United States experienced drought conditions of different extent, and nearly half of the areas were under the most severe D4 type (exceptional drought characterized by intensity). Given the diversity of land cover types and PM sources in the southern United States, the impacts of the 2011 severe drought on PM air quality are potentially important over this region but have yet to be characterized and quantified.…”

This study investigates the impacts of the 2011 severe drought in the southern United States on ground-level fine aerosol (PM 2.5 ) concentrations in the summer. The changes in surface concentrations and planetary boundary layer (PBL) budget of PM 2.5 between June 2010 (near-normal rainfall) and June 2011 (severe drought) are quantified using surface observations and the GEOS-Chem model. Observations show an average enhancement of 26% (p , 10 24 ) in total PM 2.5 over the southern U.S. (SUS) region during the drought, which is largely attributed to a ;120% increase in organic carbon (OC). Over Texas (TX) under extreme drought conditions, surface PM 2.5 shows a mean decrease of 10.7% (p , 0.15), which is mainly driven by a decrease of 26% (p , 0.03) in sulfate. Model simulations reproduce the observed relative changes in total PM 2.5 , OC, and sulfate during the drought. The model correctly identifies OC as the major contributor to the overall PM 2.5 increase over SUS and sulfate as the key driver of the PM 2.5 decrease over TX. Budget analysis suggests that increased OC emissions from wildfires (158 kt C month 21 ), enhanced SOA production (11.1 kt C month 21 ), and transboundary inflow from Mexico (18.6 kt C month 21 ) are major contributors to the increase in atmospheric OC contents over SUS. Over TX, a 70% decrease of aqueous-phase oxidation of sulfate, driven by decreasing low clouds, outweighs the combined effects of reduced wet deposition and decreased outflow as the key driver of sulfate decrease both at the surface and within the PBL.

Several environmental and economic consequences of drought and the accompanying water shortage were observed in the plain area of the Carpathian Basin in the last decades. This area is mostly used for agriculture, thus it is a key problem in the future to maintain food safety in the changing circumstances. Therefore, involvement and identification of areas affected by drought hazard and revealing steps of efficient adaptation are of high importance. In this study influence of drought severity on agricultural production is investigated in the Hungarian-Serbian cross-border area. The tendency in drought severity was analysed by PaDI and MAI drought indices. The effect of drought on agricultural production is evaluated on maize yield data as the most drought sensitive crop in the region. Increasing drought frequency and severity was indicated for the study area for the period of 1961-2012. The spatial assessment of annual PaDI maps revealed the higher exposure of the north and northeastern part of the study area to drought, where drought frequency was also experienced to be the highest. Increased sensitivity was detected based on maize yield loss after the early 1990s and annual yields were in strong connection with d rought severity. In spite of the technological development of agriculture, environmental factors still substantially affect crop yie lds. The observed unfavourable changes in the region mean that water management and spatial planning faces conceptual cha llenges to prevent and mitigate the damages of drought.
