“…Recent extreme climate events such as the 2003 heat wave in Europe (Trigo et al 2005;Fink et al 2004;Schär et al 2004;Luterbacher et al 2004;Stott et al 2004) that significantly affect human health Koppe et al 2004;Stéphan et al 2005) have led climatologists to question whether such events are unprecedented in the historical record. EMSLP provides a unique opportunity to explore the circulation patterns associated with both daily and submonthly extreme events back to the mid-nineteenth century.…”

Daily Mean Sea Level Pressure Reconstructions for the European–North Atlantic Region for the Period 1850–2003

The development of a daily historical European-North Atlantic mean sea level pressure dataset (EMSLP) for 1850-2003 on a 5°latitude by longitude grid is described. This product was produced using 86 continental and island stations distributed over the region 25°-70°N, 70°W-50°E blended with marine data from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS). The EMSLP fields for 1850-80 are based purely on the land station data and ship observations. From 1881, the blended land and marine fields are combined with already available daily Northern Hemisphere fields. Complete coverage is obtained by employing reduced space optimal interpolation. Squared correlations (r 2 ) indicate that EMSLP generally captures 80%-90% of daily variability represented in an existing historical mean sea level pressure product and over 90% in modern 40-yr European Centre for Medium-Range Weather Forecasts Re-Analyses (ERA-40) over most of the region. A lack of sufficient observations over Greenland and the Middle East, however, has resulted in poorer reconstructions there. Error estimates, produced as part of the reconstruction technique, flag these as regions of low confidence. It is shown that the EMSLP daily fields and associated error estimates provide a unique opportunity to examine the circulation patterns associated with extreme events across the European-North Atlantic region, such as the 2003 heat wave, in the context of historical events.

“…10,11 Evidence from European and American cities suggests that when outdoor temperatures are unusually high, there is a rise in hospital admissions 10,[12][13][14][15] for respiratory ailments, renal diseases, 12 and infectious diseases (both vector-borne and foodborne) and cerebrovascular accidents, including subarachnoid haemorrhage 13 and transient ischaemic attacks. [16][17][18][19][20][21][22] The risk of admission appears to be higher among the critically ill, 23 the very young, the very old, people of low socioeconomic status, 24 people with pre-existing medical conditions, 12,16 health-care workers, pregnant women 25 and people who are institutionalized, live alone or have poor mobility. 24 Hong Kong Special Administrative Region (SAR), China, has recorded one of the world's highest average increases in ambient temperature.…”

“…The T sk of local areas and T cr maintained dynamic equilibrium for heat transfer to the periphery as well as cutaneous reflex to control skin blood flow. The resultant is the combined effect of work and heat stress 37) , with the dominant effect reflected in the responses. The risk of hyperthermia ensues when excessive environmental warmth overwhelms the thermoregulatory mechanism and/or, there is impairment in heat dissipation 38) .…”

Critical Body Temperature Profile as Indicator of Heat Stress Vulnerability

2013

Extreme climatic heat is a major health concern among workers in different occupational pursuits. People in the regions of western India confront frequent heat emergencies, with great risk of mortality and morbidity. Taking account of informal occupational groups (foundry and sheet metal, FSM, N=587; ceramic and pottery, CP, N=426; stone quarry, SQ, N=934) in different seasons, the study examined the body temperature profiling as indicator of vulnerability to environmental warmth. About 3/4th of 1947 workers had habitual exposure at 30.1-35.5 °C WBGT and ~10% of them were exposed to 38.2-41.6 °C WBGT. The responses of FSM, CP and SQ workers indicated prevailing high heat load during summer and post-monsoon months. Local skin temperatures (T sk ) varied significantly in different seasons, with consistently high level in summer, followed by post-monsoon and winter months. The mean difference of T cr and T sk was ~5.2 °C up to 26.7 °C WBGT, and ~2.5 °C beyond 30 °C WBGT. Nearly 90% of the workers had T cr within 38 °C, suggesting their self-adjustment strategy in pacing work and regulating T cr . In extreme heat, the limit of peripheral adjustability (35-36 °C T sk ) and the narrowing down of the difference between T cr and T sk might indicate the limit of one's ability to withstand heat exposure.
