Shade is now avail Katabatic winds occur where air in contact with sloping ground is colder than air at the same level away from the hillside over the valley see diagram. Katabatic winds are nocturnal phenomena in most parts of the world i. Katabatic winds may lead to the formation of frost, mist and fog in valleys.
Sea breezes are the result of differential heating of the land and the sea. Sea breezes occur by day, when the land becomes warmer than the sea. Warm air from the land cannot expand into the sea as the air is cooler and more dense, so it expands up into the atmosphere. Cumulus clouds tend to form as the warm air rises over the land to about m. Air in sea breezes is cool and moist compared to the air over the land.
Sea breezes can move 70km inland in temperate climates by 9pm in the evening. Sea breezes can be noticed several kilometres out to sea. In the tropics they can be felt 20km from the land. Land breezes occur at night and in the early morning, when the land is cooler than the sea. This is because as the air cools in the night time as there is less heating from the sun it contracts.
Pressure is higher over the land than the sea. This causes the air to flow from the land to the sea which is known as a land breeze. The circulation is completed by air rising and moving towards the land at m. Cumulus clouds from where there is rising air. Land sea breeze fronts tend to only affect a small area of km out to sea, in comparison to the much larger effect of sea breezes. As well as local winds and local weather phenomena, the following list includes seasonal winds with local names:.
A cold dry wind which blows from the north-east, north or north-west in the mountainous regions of southeastern France and western Switzerland in winter months. The bise is accompanied by heavy cloud. The bora is a strong, cold and gusty north-easterly wind which descends to the Adriatic Sea from the Dinaric Alps, the mountains behind the Dalmatian coast the coast of Croatia.
It is a winter phenomenon that develops when a slow-moving depression is centred over the Plain of Hungary and western Balkans so that winds are blowing from the east towards the Dinaric Alps. These mountains form a barrier which trap the cold air to the east of them whilst the Adriatic coast remains comparatively mild. Gradually, though, the depth of the cold air increases until the air flows over passes and through valleys to reach the Adriatic Sea.
The bora begins suddenly and without warning and the cold air typically descends to the coast so rapidly that it has little time to warm up. The fastest wind speed recorded during a Chinook was mph, in Alberta, Canada. The name given to the drizzly weather with low stratus, mist or fog which occurs from time to time during the period January to April over the China Sea and in coastal areas between Shanghai and Cape Cambodia.
The strong northerly winds which blow at times over the Aegean Sea and eastern parts of the Mediterranean Sea during the period May to October. The winds are known as meltemi in Turkey. It is a result of forcing stable air over a mountain barrier. In addition, they occur over eastern Sri Lanka during the south-west monsoon. A notorious wind of the western Mediterranean which also blows across central parts of the Mediterranean Sea. It is a strong and cold wind from the north-east and occurs mainly in winter.
It is most pronounced on the island of Malta, where it sometimes reaches hurricane force and endangers shipping. The Bible tells us that the ship which carried St Paul and other prisoners across the Mediterranean en route to Rome was driven by a storm from Crete to Malta, where it was eventually wrecked.
The ship set sail from a bay called Fair Havens near Lasea on the south coast of Crete, having put into this bay to wait for favourable conditions after being delayed by contrary winds. As the bay was exposed to storms, it was not considered a safe place to remain at the time of year in question, which was either late September or early October.
The harbour at Phoenix on the south-western coast of Crete was considered a safer place to spend the winter. Soon after the ship left Fair Havens, however, a severe gale began to blow.
So violent was the storm that the sailors could do no more than drift with the wind. The Bible tells us that the ship reached Malta fourteen days later. Paul experienced a gregale. As these winds normally last no more than four or five days, the storm he experienced appears to have been unusually persistent. A dry and comparatively cool wind which blows from the east or north-east on the coast of North Africa between Cabo Verde and the Gulf of Guinea during the dry season November to March.
It brings dust and sand from the Sahara Desert, often in sufficient quantity to form a thick haze which hinders navigation on rivers. Dust and sand are sometimes carried many hundreds of kilometres out to sea. An easterly wind found in Cumbria, N. England, where the winds blow over Cross Fell and then descend into the Eden Valley.
A bank of cloud forms over the hill tops, and the roaring of the wind can be heard as far away as Penrith. The name given to the south-easterly winds which prevail in winter December to April in the Persian Gulf.
They are accompanied by gloomy weather, rain and squalls and are sometimes followed by very strong south-westerly winds called suahili. A hot, dry, dust-laden, southerly wind over Egypt, the Red Sea and eastern parts of the Mediterranean Sea ahead of eastward-moving depressions.
It occurs during the period February to June, being most frequent in March and April. In the nineteenth Century, the plague was worst in Egypt when the Khamsin was blowing. A strong south-westerly wind which blows daily over the Gulf of Aden from about hours until about noon the following day. It occurs in June, July and August during the south-west monsoon and frequently reaches gale force.
A hot, dry, southerly wind which occurs in winter and spring between Madeira and Gibraltar and along the coast of North Africa ahead of an advancing depression.
A moist wind which blows from the east over the Strait of Gibraltar. It is frequently accompanied by haze or fog and may occur at any time of year, though it is most common in the period June to October. The strength of the Levanter does not normally exceed Beaufort Force 5. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Abiotic and biotic factors work together to create a unique ecosystem.

There are two main types of weathering: chemical and physical. An example of chemical weathering is acid rain. Caused mostly by the burning of fossil fuels, acid rain is a form of precipitation with high levels of sulfuric acid, which can cause erosion in the materials in which it comes in contact. An example of physical weathering is wind blowing across the desert playas.
This process causes rocks to form a specific pyramid-like shape and they are called ventifacts. Select from these resources to teach about the process of weathering in your classroom.
