Tropical Storm Nana (2008)
Tropical Storm Nana was the fourteenth tropical storm of the 2008 Atlantic hurricane season. The storm formed in early October from a tropical wave with a nearby low pressure area. The wave moved west-northwest with a small amount of convection, before being completely organized enough to become a tropical depression while west of the Cape Verde Islands. It became a tropical storm later that same day, and began weakening almost right away thereafter as it moved in to an area of higher vertical wind shear. The storm finally died out early on October 15. Nana did not have an effect on any land areas or ships.
A tropical wave moved west, awat from the western coast of Africa on October 6. This wave continued moving west with just a little bit of convection until October 8, when organized cloud bands began to form around its low-level center. The wave continued moving westward and organizing until it was called a tropical depression early on October 12, west of the Cape Verde Islands. It began moving towards the west-northwest because of a weakness in the subtropical ridge while becoming stronger to its strongest point of . As it did so, it went into an area of strong upper level winds, which began moving the thunderstorm clouds to the east of the center of circulation. Just twelve hours later, it had weakened back into a tropical depression, and by October 14 it had weakened back to just little more than a low-level cloud swirl. It died out early the next day as it combined itself with a powerful front, east-northeast of the Leeward Islands.
Tropical Storm Nana's formation was expected for a few days before it actually developed. Movement and strength predictions were also better than the long term average. Because of Nana's short life the sample size is not very meaningful. Tropical Storm Nana stayed in the middle of the Atlantic and never came near land. As a result, it had no known impact. No ships reported strong winds that came from the tropical storm.
Sample size
In statistics, the sample size of a sample is the number of observations that make up it. It is usually denoted as "n", a positive integer (natural number).
For large sample sizes of 30 or more, statistics describing the samples tend to be more reliable. As a result, statistical analysis is easier with large samples than with small samples. In research, sample sizes are often calculated before the experiment are conducted to make sure that the desired conditions can be met.
Accumulated Cyclone Energy
Accumulated cyclone energy (ACE) is a measure used by the National Oceanic and Atmospheric Administration (NOAA) to show the activity of each tropical cyclones and entire tropical cyclone seasons, particularly the Atlantic hurricane seasons. It uses an estimation of the energy used by a tropical system over its lifetime and is calculated in every six hours.
Bohemian F.C.
Bohemian F.C. is a football club in Dublin, Ireland. They play in the League of Ireland. The club is owned by the club members.
The club was founded in 1890. They were member of the Irish Football League from 1902 to 1911 and 1912 to 1920. During this time the greatest success was the Irish Cup in 1908 and were five times runner-up. It was a founding member of the League of Ireland in 1921. The club is one of only two clubs to have been members of the League of Ireland since it was founded (the other being Shelbourne). Bohemians is the only club who always played in the top division. Till 1969 they were an amateur team. Today they are a professional club.
Bohemians play their home matches at Dalymount Park in the Northside neighbourhood of Phibsborough. Their club colours are red and black. Bohemians supporters often refer to their club by a number of nicknames including 'Bohs', 'The Gypsies' and 'The Big Club'. The big rival is Shamrock Rovers a club from Dublins south side.

Eurasian Avars
The Avars were a powerful semi-nomadic group. Their leader was called a "Khagan". They could be found in Central and Eastern Europe during the 6th century. They were a union of White Huns and Rourans. Avars of the Caucasus are remnants of White Huns, have a direct contact with Avar Empire of Europe. They were predominantly ethnic Mongols.
2006 Central Pacific cyclone
The 2006 Central Pacific cyclone, also called 91C.INVEST or Storm 91C, was a strange weather event in 2006. Forming on October 30 from a mid-latitude cyclone in the north Pacific mid-latitudes, it moved over waters warmer-than-normal. It got some characteristics more normal for subtropical or even tropical cyclones. However, as it came closer to western North America, it fell apart. Moisture from its remains then caused a lot of rainfall in British Columbia.
A cut-off extratropical cyclone over the central north Pacific moved into a place with sea surface temperatures as high as 2 °C above normal for two days. By October 31 the system had gotton convection, a warmer-than-normal core, and an eye-like characteristic. During this time it had moved east, then northeast, and then northwest.
On November 1, the system had estimated winds of 100 km/h (60 mph) and its most developed convection. After that, it slowly weakened, moved counter-clockwise, and headed east towards the west coast of North America. On November 2, wind shear started affecting the storm, and all convection was gone by the next day, when it was located roughly 520 mi (840 km) off the coast of Oregon.
This system's center of circulation passed south of observation buoy 46637 on November 1. The buoy's lowest pressure reading was 989 mb/hPa. Other buoys indicated that a rather large area of low pressure was associated with the system. Buoy 46637 was not at the system's center of circulation, so it is possible that this system had a lower minimum pressure than was actually measured.
As a result, to the weather system, the American National Weather Service gave out wind watches for the Oregon Coast. The system brought heavy rain to parts of Vancouver Island.
If Storm 91C is really a tropical or subtropical cyclone, it has several records. Since right now it is not officially either, its holding these records is also unofficial. Because the storm formed at 36°N, this system is the northernmost formation in the eastern north Pacific basin. The previous record-holder was Tropical Storm Wene, which formed at 32°N before crossing the dateline. In addition, this system's track data shows that it crossed from the central to the east Pacific because it formed at longitude 149°W and dissipated at 135°W. Only two other known tropical cyclones had done that before.
This system has been thought to be a tropical, subtropical, or extratropical cyclone.
Mark Guishard, a meteorologist with Bermuda Weather Service, had the opinion that the system had finished tropical cyclogenesis and was a tropical cyclone. Meteorologist Mark Lander thought that cloud tops were similar to several Atlantic hurricanes, Hurricane Vince in example. James Franklin, a meteorologist at the National Hurricane Center, thought that:
The system was of frontal origin... the frontal structure was eventually lost... The convective structure resembled a tropical, rather than subtropical cyclone, and the radius of maximum winds (based on QuikSCAT) was very close to the center, also more typical of tropical cyclones... on balance, it was more tropical than subtropical.
