2. 1. Short-term effects of ambient temperature on daily deaths and hospital admissions

   Author : Joacim Rocklöv; Bertil Forsberg; Jan Semenza; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; temperature; humidity; weather; climate; climate change; hot; heat; cold; cold spell; cold wave; heat wave; health; hospitalization; hospital admission; death; mortality; morbidity; epidemiology; environmental epidemiology; time series; Public health medicine research areas; Folkhälsomedicinska forskningsområden; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Abstract : Background: Incidence of death and hospitalizations have been observed to depend on short-term changes in weather and to increase with extreme temperatures. This thesis aims to strengthen the scientific knowledge on the relationship between temperature and daily deaths, but also the relationship between temperature and daily hospital admissions.

4. 2. Latent Heat Thermal Energy Storage for Indoor Comfort Control

   Author : NingWei Justin Chiu; Viktoria Martin; Motoi Yamaha; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Phase Change Material; Indoor Comfort; Heat Transfer; Termisk Energilagring; Fasändringsmaterial; Inomhuskomfort; Värmeöverföring;

   Abstract : Equating Earth’s existence to 24 hours, we, the Homo sapiens, came about in the last four seconds. Fossil fuel came to our knowledge with mass extraction dating from the Industrial Revolution two centuries ago, in other words 4 milliseconds out of Earth’s 24-hour equivalent lifetime. READ MORE

5. 3. Atmosphere-ocean Interactions in Swell Dominated Wave Fields

   Author : Alvaro Semedo; Anna Rutgersson; Oyvind Saetra; Piero Lionello; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Waves; Wind sea; Swell; Swell propagation; MABL; Air-sea interaction; Momentum flux; Wave climate; Coupling; Wave age; Empirical Orthogonal functions; Wave model; Climate model; WAM; RCA; wave heights; Meteorology; Meteorologi; Meteorologi; Meteorology;

   Abstract : Ocean wind waves represent the atmosphere-ocean boundary, playing a central role in the air-sea exchanging processes. Heat, mass and momentum are transferred across this boundary, with waves mediating the exchange of principally the momentum between the winds and the ocean surface. During the generation process waves are called wind sea. READ MORE

6. 4. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer

   Author : Erik Olof Nilsson; Anna Rutgersson; Harm Jonker; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Waves; Growing sea; Swell; Marine boundary layer; Air-sea interaction; Mixing; Momentum flux; Wind stress; Flux attenuation; Sensor separation; Large eddy simulation; Multiresolution analysis; Coupling; Wave model; Climate model; Wave age; Meteorology; Meteorologi;

   Abstract : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. READ MORE

7. 5. Introducing Surface Gravity Waves into Earth System Models

   Author : Lichuan Wu; Anna Rutgersson; Erik Sahlée; Peter Janssen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface gravity waves; Air-sea interaction; Earth-System Model; Atmospheric mixing; Upper-ocean turbulence; Meteorologi; Meteorology;

   Abstract : Surface gravity waves alter the turbulence of the bottom atmosphere and the upper ocean. Accordingly, they can affect momentum flux, heat fluxes, gas exchange and atmospheric mixing. However, in most state-of-the-art Earth System Models (ESMs), surface wave influences are not fully considered or even included. READ MORE
