Climate Of Lisbon
Lisbon and its metropolitan area feature a mild Mediterranean climate (Köppen: ''Csb/Csa''), with short, mild and rainy winters and warm to hot, dry summers. According to the Troll-Paffen climate classification, Lisbon has a ''warm-temperate subtropical'' climate (''Warmgemäßigt-subtropisches Zonenklima''). According to the Siegmund/Frankenberg climate classification, Lisbon has a subtropical climate. Classifications Temperature Normals Lisbon has mild to warm, moderated temperatures. Winters are mild especially for its latitude with average daytime temperatures between and nighttime lows between . Summers are warm to hot, but due to the upwelling phenomena in the western coasts of its metropolitan area, maxima in summer fluctuates considerably depending on the location. Regions across the Tagus Estuary, for example, typically average around maxima in July and August, while areas west of the city and close to the coast, such as Cascais or Sintra, will usually average around ...

Saharan Air Layer
The Saharan Air Layer (SAL) is an extremely hot, dry and sometimes dust-laden layer of the atmosphere that often overlies the cooler, more-humid surface air of the Atlantic Ocean. It carries upwards of 60 million tonnes of dust annually over the ocean and the Americas. This annual phenomenon sometimes cools the ocean and suppresses Atlantic tropical cyclogenesis. The SAL is a subject of ongoing study and research. Its existence was first postulated in 1972. Creation The dust cloud originates in Saharan Africa and extends from the surface upwards several kilometers. As the dust drives, or is driven out over the Atlantic ocean, it is lifted above the denser marine air. This atmospheric arrangement is an inversion where the temperature actually increases with height, as the boundary between the SAL and the marine layer suppresses or "caps" any convection originating in the marine layer. Since it is dry air, the lapse rate within the SAL itself is steep, that is, the temperature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sintra Mountains
The Sintra Mountains ( pt, Serra de Sintra), is a mountain range in western Portugal. Its highest point is at 529 meters (1,736 ft) near Sintra. The range covers about 16 kilometers (10 mi) from the resort town of Sintra to ''(Cape Roca)'' on the Atlantic Ocean. It was known to the Ancient World as Lunae Mons (mountain of the Moon) and was the legendary retreat of Diana the Huntress (known as Cynthia to the Romans, from the Greek ''Κύνθια'', hence Çintra). It has a rich fauna, foxes, genet, moles, salamanders, peregrine falcons, vipers and various species of scaly reptiles. Its climate is temperate with many oceanic influences and hence presents a higher rainfall than the remaining area of Lisbon. It also has a unique vegetation. About nine hundred plant species are indigenous, ten percent of which are endemic. Namely oak, cork oak and pine wood. It is the target of several sightseeing tours. It is also visited by climbing and mountaineering practitioners, si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabo Espichel
Cabo Espichel is a cape situated on the western coast of the civil parish of Castelo, municipality of Sesimbra, in the Portuguese district of Setúbal. History Following the Chalcolithic, human tribes began to look for elevated locations in order provide a natural defense; there are vestiges encountered in the area of Outeiro Redondo and Zambujal, that indicate this preoccupation and conflicts.Mário Nuno Antas and Sofia Ferreira (2011), p.9 During the Iron Age, there are documented references to the lands of Risco, farther to the west of Cabo Espichel, that was a largest undefended settlement at the time. Avieno in ''Orla Marítima'' named Cabo Espichel, ''Cabo Cêmpsico'', and was probably because the name was associated with the peoples that lived in the vicinity. Later, the geographer Strabo called this area ''Promontorium Barbaricum''. At a time when Roman settlement persisted in the Iberian peninsula, the Roman presence on the cape was limited. This can be explained by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Setúbal Peninsula
The Setúbal Peninsula (Portuguese: ) is a peninsula in the Lisbon Region of Portugal. The peninsula is named after one of its larger cities, Setúbal, and is bordered by three bodies of water, the Atlantic Ocean in the west and southwest, the Tagus Estuary to the north and the Sado Estuary to the southeast. The region can be divided into two different orographic zones: the mountainous southwest, formed by the Arrábida mountain range, cut by valleys and hills, with altitudes between , and the remaining extensive flat areas, part of the Tagus floodplain A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudi ....

Hong Kong Observatory
The Hong Kong Observatory is a weather forecast agency of the government of Hong Kong. The Observatory forecasts the weather and issues warnings on weather-related hazards. It also monitors and makes assessments on radiation levels in Hong Kong and provides other meteorological and geophysical services to meet the needs of the public and the shipping, aviation, industrial and engineering sectors. Overview The Observatory was established on 2 March 1883 as the Hong Kong Observatory by Sir George Bowen, the 9th Governor of Hong Kong, with (1852–1941) as its first director. Early operations included meteorological and magnetic observations, a time service based on astronomical observations and a tropical cyclone warning service. The Observatory was renamed the Royal Observatory Hong Kong () after obtaining a Royal Charter in 1912. The Observatory adopted the current name and emblem in 1997 after the Handover of Hong Kong, transfer of Hong Kong's sovereignty from the UK ...

Drizzle
Drizzle is a light precipitation consisting of liquid water drops smaller than those of rain – generally smaller than in diameter. Drizzle is normally produced by low stratiform clouds and stratocumulus clouds. Precipitation rates from drizzle are on the order of a millimetre (0.04 in) per day or less at the ground. Owing to the small size of drizzle drops, under many circumstances drizzle largely evaporates before reaching the surface and so may be undetected by observers on the ground. The METAR code for drizzle is DZ and for freezing drizzle is FZDZ. Effects While most drizzle has only a minor immediate impact upon humans, freezing drizzle can lead to treacherous conditions. Freezing drizzle occurs when supercooled drizzle drops land on a surface whose temperature is below freezing. These drops immediately freeze upon impact, leading to the buildup of sheet ice (sometimes called black ice) on the surface of roads. Occurrence Drizzle tends to be the most fre ...

Low-pressure Area
In meteorology, a low-pressure area, low area or low is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure areas are commonly associated with inclement weather (such as cloudy, windy, with possible rain or storms), while high-pressure areas are associated with lighter winds and clear skies. Winds circle anti-clockwise around lows in the northern hemisphere, and clockwise in the southern hemisphere, due to opposing Coriolis force, Coriolis forces. Low-pressure systems form under areas of wind divergence that occur in the upper levels of the Atmosphere of Earth, atmosphere (aloft). The formation process of a low-pressure area is known as cyclogenesis. In Meteorology#Dynamic meteorology, meteorology, atmospheric divergence aloft occurs in two kinds of places: * The first is in the area on the east side of upper Trough (meteorology), troughs, which form half of a Rossby wave within the Westerlies (a trough (meteorology), trough with la ...

Azores High
The Azores High also known as North Atlantic (Subtropical) High/Anticyclone or the Bermuda-Azores High, is a large subtropical semi-permanent centre of high atmospheric pressure typically found south of the Azores in the Atlantic Ocean, at the Horse latitudes. It forms one pole of the North Atlantic oscillation, the other being the Icelandic Low. The system influences the weather and climatic patterns of vast areas of North Africa and Southern Europe, and to a lesser extent, eastern North America. The aridity of the Sahara Desert and the summer drought of the Mediterranean Basin is due to the large-scale subsidence and sinking motion of air in the system. In its summer position, the high is centered near Bermuda, and creates a southwest flow of warm tropical air toward the East Coast of the United States. In summer, the Azores-Bermuda High is strongest. The central pressure hovers around 1024 mbar (hPa). This high-pressure block exhibits anticyclonic behaviour, circulating the air ...
