A weather station has machines that measure wind speed, wind direction, temperature, barometric pressure, and humidity of the air around them. There are many ways to do this with instruments such as barometers (air pressure), psychrometers (humidity), anemometers (wind speed) and cielometers (electronic, for cloud cover). Many weather stations have no people; they report their measurements automatically.
Atmospheric pressure
Atmospheric pressure is a force in an area pushed against a surface by the weight of the atmosphere of Earth, a layer of air. The air is not distributed evenly around the globe. It moves, and at different times, the layer of air is thicker in some places than in others. Where the layer of air is thicker, there is more air. Since there is more air, there is a higher pressure in that spot. Where the layer of air is thinner, there is a lower atmospheric pressure.
At higher altitude, the atmospheric density and pressure are lower. This is because high places do not have as much air above them, pushing down.
Barometers can be used to measure atmospheric pressure. There is the same atmospheric pressure from all directions. The SI unit for pressure is hPa. Other units such as Bar (unit) and torr are used for various applications.

The average temperature is 8 °C and the amount of rain and snow every year (annual precipitation) is 700 mm.
The "Karl-Marx-Monument" has been an attraction of the city since 1971. The 7,10 meter high statue was created by the Russian artist Lev Kerbel. The inhabitants of Chemnitz call it "Nischel", which means "head" in the dialect of the area.
The "Roter Turm" (the "red tower")is one of Chemnitz's oldest sites; it was built in the 12th or 13th century and was once part of the city wall.
The town hall of Chemnitz consists of two buildings. The old town hall was built in the 15th century. The new townhall, on the other hand, was built at the beginning of the 20th century and was designed by Richard Möbius. The new town hall was erected next to the old one.
One of the new attractions of the city is "das Tietz". The former department store was constructed in 1912/1913. Today the Museum for Natural History, the public library, an adult education centre, a gallery and the "Petrified Forest" are here.
Chemnitz had an ICE connection for a short time, until 2006. Chemnitz is part of the railway line Dresden - Chemnitz - Hof - Nuremberg which is called 'Franken - Sachsen - Magistrale'. Today an InterRegioExpress services Dresden, Nuremberg and Leipzig. There are regional train (RegionalBahn) connections to the Ore Mountains and to Elsterwerda.
Here are listed on the most important roads of the metropolitan:

Small intestine
The small intestine is between the stomach and the large intestine, and is where most of the digestion and absorption happen. In humans over five years old, the small intestine is about 7.5 meters long.
The small intestine has three regions: the duodenum, the jejunum and the ileum.
Songwriter
A songwriter is a writer who creates songs. A songwriter generally writes songs for popular music, rather than art songs or classical music. Many songwriters are also singers, and perform the songs they write - they are called singer-songwriters. Other songwriters have their songs performed by other singers.
The history of writing songs is thousands of years old. Scholars believe that men and women may have created and sung songs even at the time of prehistory. Many modern bands have one or two members who write songs for the band. Others have more members contribute songs, or give the whole band credit for writing. Others perform songs by outside writers.
Hezbollah
Hezbollah (, meaning "Party of God") is an Islamic political party and paramilitary organization in Lebanon. It was formed in Lebanon in 1982, during the Lebanese Civil War. The leader of Hezbollah is currently Hassan Nasrallah.
Hezbollah's main goals during the Civil War were to fight against Western influences and create an Islamic state in Lebanon .Its members are Shia Muslims which are the largest Islamic denomination in Lebanon. It is also supports Arab nationalism. It wants freedom for the Palestinian people in Palestine. Because of this, it believes that the State of Israel should not exist, and fights against it. Over the years, the Hezbollah militia has fought a guerrilla war against the Israeli Army along the border in southern Lebanon. It often attacks Israel's military positions by firing rockets across Israel's northern border.
Hezbollah is supported by Syria, Iran, Russia, Lebanon and Iraq.
To destroy Hezbollah bases, Israel has responded in different ways; for example, air strikes on sites in Lebanon and sending ground troops into Southern Lebanon. In 2000, Israel withdrew its troops from the "security zone" in Southern Lebanon, but not from a sliver of land called Shebba Farms. This fertile area was kept under Israeli occupation. The border stayed relatively quiet until July 2006, except for targeted assassinations and kidnappings by Israel. In July, Hezbollah captured two Israeli soldiers. This led to the 2006 Lebanon War, in which Hezbollah rockets reached deep into Israel.
A few governments consider Hezbollah a terrorist group. The majority do not. Among those who consider it to be a terrorist group are the United States, Bahrain, Canada, Japan, the Netherlands and Israel. The European Union and the United Kingdom consider Hezbollah's military branch to be a terrorist group, but not the political party. Lebanon considers Hezbollah to be a legitimate resistance movement. This view is shared by Syria, Iran and all other countries in the Arab world.Russia considers Hezbollah as a legitimate sociopolitical organization while China remains neutral, and maintains contacts with Hezbollah. Other countries that do not consider Hezbollah a terror organization includes Cuba, Iran, Iraq, North Korea, and others.
