The Indian summer monsoon (ISM) is a prominent feature of the summer circulation in the Northern Hemisphere (NH) and has been found to modulate the weather and climate conditions in many remote regions. This study investigates the most recurrent patterns of summertime midlatitude circulation, over the eastern Mediterranean (EM) and also globally, that are most associated with the ISM. Monthly data of 44 summers from the ERA40 dataset are used and two multidimensional statistical methods, the Principal Component Analysis (PCA) and Canonical Correlation Analysis (CCA), are implemented. The ISM is found to be related to subsidence anomalies in the middle and more extendedly in the upper troposphere over the central and eastern Mediterranean and with an Etesian-like pattern regarding the field of the lower troposphere winds. An equatorial Rossby wave pattern, extending westward from an ISM heat source up to EM and N. Africa, was identified to be associated with the variability of ISM. The observed relationship between the ISM and the EM circulation features can be attributed to this equatorial Rossby wave response to the monsoon forcing. CCA implementation revealed the interconnection of the aforementioned PCA results with an ISM action center over the northern Arabian Sea and the monsoon trough region.
In this study the impact of the Indian summer monsoon on the large scale variability of the atmospheric circulation over the Mediterranean is investigated on an inter-annual time scale. Composite and correlation analysis results are presented, outlining different circulation patterns in the upper and lower troposphere for strong and weak monsoon years respectively. For this purpose ERA-40 Reanalysis monthly mean data at various isobaric levels together with the standardized All India Rainfall Index for boreal summer (June-July-August-September) of a 44-year period were employed. During strong monsoon years many atmospheric circulation systems appear strengthened over Eurasia, resembling a well-organized Rossby wave train over the area. In the upper troposphere a meridional shift of the jet streams over the examined area was also identified during extreme monsoon years. On the other hand, in the lower troposphere enhanced northerlies (Etesians) appear to dominate over Eastern Mediterranean along with intensified subsidence during strong monsoon years.
This paper will present a medical network in Latin America. This network will provide in rural and underserved areas an appropriate health care from distance. The medical applications will vary from gynaecology, paediatrics, cardiology to typical infectious diseases for the region such as malaria and tuberculosis. The examinations will involve ultrasound examination, electrocardiogram and blood imaging when applicable. Our medical tele-consulting tool will be used for that purpose. The medical network aims to connect isolated areas in Amazon over European satellite technology providing broadband communication and quality of services (QoS) for real-time data transmission and video/audio conference
TraumaStation is a portable medical device which covers the mobility of the medical doctors as well as integrates the diversity of telemedicine devices. Many portable telemedicine devices has been developed the last years in order to help patients in remote areas or in emergency situationns. The medical TraumaStation is a light portable tele-medical first-aid device, which provides the physicians with an ultrasound, electrocardiogram, blood pressure, oxygen meter apparatus all in a suitcase. In addition, the portable device is equipped with all available telecommunication gateways (e.g. GSM, UMTS, ISDN, DSL, Satellite) providing a great communication convenience to the physicians utilizing XMMP instant messaging protocols and real time video conference.
