Svenska Högarna
Svenska Högarna () is a small group of islands and a lighthouse located east of Möja in the Stockholm archipelago. History The lighthouse is located on the largest island ''Storön'', and is the only lighthouse in Stockholm archipelago with the classic iron design of architect Nils Gustaf von Heidenstam. Before the lighthouse was built there had been a checkered day beacon on the island, it is now located at the island of Storkläppen in Östergötland. Svenska Högarna lighthouse was lit in 1874 with a colza oil lamp. In 1887 a paraffin lamp was installed, in 1966 it was electrified and in 1986 solar cells were put in use to generate power. The island is staffed with a weather station. It is frequently reported as a wind observation station in the Shipping Forecast of the Swedish Meteorological and Hydrological Institute. Since 1994 the lighthouse is owned by a foundation called "Edward Sjöbloms stiftelse". All of the islands are a nature reserve with sparse vegetation. O ...

Stockholm Archipelago
The Stockholm Archipelago () is the largest archipelago in Sweden, and the second-largest archipelago in the Baltic Sea (the largest being the Archipelago Sea across the Baltic in Finland). Part of the archipelago has been designated as a Ramsar site since 1989. Stockholm Archipelago has been found to have slightly over 24,000 islands, islets and skerries and covers approximately 1,700 km² of which approximately 530 km² is land. There are around 10,000 permanent residences and 50,000 holiday homes in the archipelago. Residents are found on all the larger islands closest to the coast that have fixed bridges or ferry connections with road ferries, such as Vaxholm, Ingarö, Värmdö, Yxlan, Blidö, Ljusterö and Väddö, but also on many of the larger islands farther out from the coast, as Ingmarsö, Möja, Runmarö, Nämdö, Ornö and Utö, which are served by passenger ships with fixed itineraries. Water The water has a pH value of 7.0 (neutral) or slightly lowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swedish Meteorological And Hydrological Institute
The Swedish Meteorological and Hydrological Institute (, SMHI) is a Swedish government agency and operates under the Ministry of Climate and Enterprise. SMHI has expertise within the areas of meteorology, hydrology and oceanography, and has extensive service and business operations within these areas. History On 1 January 1873, Statens Meteorologiska Centralanstalt was founded, an autonomous part of the Royal Swedish Academy of Sciences, but the first meteorological observations began on 1 July 1874. It was not until 1880 that the first forecasts were issued. The latter will be broadcast on Stockholm radio from 19 February 1924.. In 1908, the Hydrographic Office (''Hydrografiska byrån'', HB) was created. Its task is to scientifically map Sweden's freshwater and collaborate with the weather service in taking certain weather observations such as precipitation and snow cover. In 1919, the two services merged and became the ''Statens meteorologisk-hydrografiska anstalt'' (SMHA). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses In Sweden
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), lenses and to serve as a beacon for navigational aid for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and the advent of much cheaper, more sophisticated, and more effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and promontory, prom ...

Seasonal Lag
Seasonal lag is the phenomenon whereby the date of maximum average air temperature at a geographical location on a planet is delayed until some time after the date of maximum daylight (i.e. the summer solstice). This also applies to the minimum temperature being delayed until some time after the date of minimum insolation. Cultural seasons are often aligned with annual temperature cycles, especially in the agrarian context. Peak agricultural growth often depends on both insolation levels and soil/air temperature. Rainfall patterns are also tied to temperature cycles, with warmer air able to hold more water vapor than cold air. In most Northern Hemisphere regions, the month of February is usually colder than the month of November despite February having significantly later sunsets and more daylight overall. Conversely, the month of August is usually hotter than the month of May despite August having later sunrises, increasingly earlier sunsets, and less daylight overall. The f ...

Diurnal Temperature Variation
In meteorology, diurnal temperature variation is the variation between a high air temperature and a low temperature that occurs during the same day. Temperature lag Temperature lag, also known as thermal inertia, is an important factor in diurnal temperature variation. Peak daily temperature generally occurs ''after'' noon, as air keeps absorbing net heat for a period of time from morning through noon and some time thereafter. Similarly, minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long. The analogous annual phenomenon is seasonal lag. As solar energy strikes the Earth's surface each morning, a shallow layer of air directly above the ground is heated by conduction. Heat exchange between this shallow layer of warm air and the cooler air above is very inefficient. On a warm summer's day, for example, air temperatures may vary by from just above the ground t ...

Oceanic Climate
An oceanic climate, also known as a marine climate or maritime climate, is the temperate climate sub-type in Köppen climate classification, Köppen classification represented as ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool to warm summers and cool to mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 40 and 60 degrees latitude, with subpolar versions extending to 70 degrees latitude in some coastal areas. Other varieties of climates usually classified together with these include subtropical highland climates, represented as ''Cwb'' or ''Cfb'', and subpolar oceanic or cold subtropical highland climates, represented as ''Cfc'' or ''Cwc''. Subtropical highland climates occur in some mountainous parts of the subtropics or tropics, some of which have monsoon influence, while their cold variants an ...

Humid Continental Climate
A humid continental climate is a climatic region defined by Russo-German climatologist Wladimir Köppen in 1900, typified by four distinct seasons and large seasonal temperature differences, with warm to hot (and often humid) summers, and cold (sometimes severely cold in the northern areas) and snowy winters. Precipitation is usually distributed throughout the year, but often these regions do have dry seasons. The definition of this climate in terms of temperature is as follows: the mean temperature of the coldest month must be below or depending on the isotherm, and there must be at least four months whose mean temperatures are at or above . In addition, the location in question must not be semi-arid or arid. The cooler ''Dfb'', ''Dwb'', and ''Dsb'' subtypes are also known as hemiboreal climates. Although amount of snowfall is not a factor used in defining the humid continental climate, snow during the winter in this type of climate is almost a guarantee, either intermitte ...

Giant's Kettle
A giant's kettle, also known as either a giant's cauldron, moulin pothole, or glacial pothole, is a typically large and cylindrical Pothole (landform), pothole drilling, drilled in solid rock (geology), rock underlying a glacier either by water descending down a deep Moulin (geomorphology), moulin or by gravel rotating in the bed of Subglacial stream, subglacial meltwater stream.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The interiors of potholes tend to be smooth and regular, unlike a plunge pool. Formation Giant's kettles are formed while a bedrock surface is covered by a glacier. Water, produced by the thawing of the ice and snow, forms streams on the surface of the glacier, which, having gathered into their courses a certain amount of Moraine, morainic debris, finally flow down a crevasse as a swirling waterfall, cascade or Moulin (geomorphology), moulin. ...

Nature Reserve
A nature reserve (also known as a wildlife refuge, wildlife sanctuary, biosphere reserve or bioreserve, natural or nature preserve, or nature conservation area) is a protected area of importance for flora, fauna, funga, or features of geological or other special interest, which is reserved and managed for purposes of Conservation (ethic), conservation and to provide special opportunities for study or research. They may be designated by government institutions in some countries, or by private landowners, such as charities and research institutions. Nature reserves fall into different IUCN protected area categories, IUCN categories depending on the level of protection afforded by local laws. Normally it is more strictly protected than a nature park. Various jurisdictions may use other terminology, such as ecological protection area or private protected area in legislation and in official titles of the reserves.
