  1. 1. Boundary Layer Studies above lake Erken using Modelling and UAV

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Oliver Nordvall; [2020]
    Keywords : Internal Boundary Layer; UAV; Sea Breeze Circulation; Numerical Simulation; WRF; lake Erken; Internt gränsskikt; UAV; Sjöbris; Numerisk simulation; WRF; Erken;

    Abstract : Internal boundary layers (IBLs) above lakes, created primarily by the autumn differential of land and lake surface temperatures, present a unique way of studying the lake-atmosphere coupling within the boundary layer. The small and mobile unmanned aerial vehicles (UAVs) contribute to new research areas within the boundary layer, offering high spatial resolution measurements to complement already existing observations.

  2. 2. An Investigation of the Relation between Sea Breeze Circulation and Diurnal Variation of Methane at a Swedish Lake

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Martin Svensson; [2015]
    Keywords : WRF model; Sea breeze; methane emission; diurnal variation; internal boundary layer; WRF-modellen; sjöbris; metanemission; dygnsvariation; internt gränsskikt;

    Abstract : Methane measurements over lake Tämnaren show a pronounced diurnal variation with high values at night and low values during daytime. The atmosphere over the lake and its surroundings is simulated with two different settings and resolutions of the WRF model during a period of eight days in May 2011 to investigate if a lake/land breeze circulation could be the cause of the observed methane variation.

  3. 3. An Analysis of the Local Weather Around Longyearbyen and an Instrumental Comparison

    University essay from Institutionen för geovetenskaper

    Author : Charlotta Petersson; [2007]
    Keywords : meteorology; Svalbard; the Arctic; Longyearbyen; local weather; channeling effects; sea breeze; inversion; case study; instrumental comparison;

    Abstract : Three different studies have been made; an analysis of the general weather situation at three weather stations in Svalbard, close to the main settlement Longyearbyen; an instrumental comparison between three weather stations operating at nearly the same place during a few days in October 2006; and a case study of a weather station at the mountain Breinosa compared to the station in the valley beneath. The analysis of the general weather at the three stations, Adventdalen (data used from 2004-2006), Svalbard Airport (data used from 1994-2004) and Gruvefjellet (data used from 2002-2005) showed that it is clear that the local surroundings do contribute to a more locally produced weather.

  4. 4. The wind field in coastal areas

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Niklas Sondell; [2001]
    Keywords : coastal meteorology; internal boundary layer; effect of surface properties; wind field; stability effects;

    Abstract : The land-sea transition in coastal areas makes the meteorological conditions rather complex and the structure of the coastal boundary layer is important for many reasons. Two examples are air pollution dispersion and wind energy potential. The wind field off the coast when offshore flow is present has been studied. READ MORE
