    Why don't I feel the cold?

    in Spring Weather Discussion

    Posted · Edited by Konstantinos

    Hi Karyo, i hope we are just the exception to the rule... Just worrying a little about the blood pressure...

     

    About the heat, i feel it early, but i am used to it, without much problem... Just cold shower every day or maybe 2 times per day, plus air conditioning and that's all.

    Why don't I feel the cold?

    Hi all... I am Greek man 30 years old living in Germany...

    While during the nights and especially during 5-7 am i feel the cold, during the days the situation is different.

    I need 12 degrees C, to feel cold with short sleeve shirt and there will be the need to wear long sleeve shirt and then i need 7-8 degrees C to wear a jacket, while Germans wear long sleeve shirt with jacket from 17-18 degrees.

    So everything is ok with me, i am just different or i have a health problem? Soon, I am gonna have health exams, so what exactly i have to focus on?

    Thanks in advance.

    Living in river in Germany... Any possible problem?

    in Weather Around The World

    Posted

    I have found an apartment that is located exactly above the river Rhine in Mannheim, Germany.

     

    See an image here: https://i.imgur.com/Xo8MfeC_d.jpg?maxwidth=640&shape=thumb&fidelity=medium

     

    Before i sign and pay, i should be sure there will not be any serious problem, living in this situation. So what is your opinion? It is exactly like living far from river or it is completely different?

     

    What about some annoying insects, like mosquitoes, or american cockroaches or german cockroaches? What about spiders? Generally speaking, in all Germany what is the "boss" of these animals?

     

    I have the following experiences:

     

    Athens, Greece: American cockroaches

    Countryside, Greece: Spiders

    Toronto, Canada: Bed bugs

    Gdansk, Poland: Cockroaches (smaller than the american ones, maybe german)

     

    So what is the "boss" of these animals in Germany, and especially in Mannheim?

     

    Also what about living in enviroment with high amounts of moisture and humidity? There should be some problems? What about allergies?

     

    And what about the pollution of the river?

     

    Since the position of the apartment is high, i am not afraid of flooding or overflowing.

     

    Thanks in advance.

    Cyclone Phenomena

    in Hurricanes, Cyclones and Extreme weather worldwide

    Posted · Edited by Konstantinos

    In this thread we will discuss about cyclone phenomena, and I start:

    1) When two cyclones are met and merge and create a stronger cyclone, how this phenomenon is called?

    2) When two cyclones are met and collide and both are impoverished, how this phenomenon is called?

    3) When a cyclone is divided into two separate cyclones, how this phenomenon is called?

    4) When a cyclone changes ocean (for example from Pacific to Atlantic) or changes part of ocean (from hurricane in north - eastern Pacific to typhoon in north - western Pacific), how this phenomenon is called?

    So, let's discuss... Say other phenomena too... Can a cyclone have two eyes?

    Super Typhoon Nepartak

    in Hurricanes, Cyclones and Extreme weather worldwide

    Posted

    Taiwan is preparing for the arrival of Nepartak, a massive typhoon that is expected to cause heavy rains and flooding.

    Typhoons are common in Taiwan - category 5 typhoons, though, are not that usual. Since 1950 there have been 18 cyclones of this most violent category, and Super Typhoon Nepartak would be number 19.

    It is the first named storm of 2016 and is currently a category 5, as defined by the Saffir-Simpson international scale.

    Even though the major El Nino of last year has now collapsed, the northwest Pacific typhoon season is having its second slowest start in nearly 70 years. That will be of no comfort to the inhabitants of Taiwan who can expect the onset of typhoon weather later on Thursday.

    Taitung and Hualien counties in eastern Taiwan are likely to be the first to be hit by Nepartak. They contain a long, low river valley so flooding is likely. The forecast rainfall is expected to be at least 300mm.

    Current measurements by NASA suggest cloud tops of 17,000 metres, or 56,000 feet, which mean that thunderheads around the typhoon's eye are punching through the top of the atmosphere. Rainfall rates over the ocean could be as high as 190mm per hour.

    As Nepartak's eye makes landfall, it will lift the Pacific's surface by between one and two metres in what is known as a "storm surge". This is often the most devastating element of a typhoon, being similar to a small tsunami.

    In the case of Super Typhoon Nepartak, the wind could also be destructive. Steady winds of 230 kilometres an hour will be boosted by gusts as high as 280km/h.

    Curiously, this is the second typhoon called Nepartak, the first being a mere category 1 storm that hit the Philippines in November 2003.

    Appropriately, the epithet Nepartak is derived from the name of a conquering warrior from the island of Kosrae in Micronesia.

    Nepartak is likely to lose a lot of energy over Taiwan, but it is forecast to regain some strength over the Taiwan Strait.

    The Chinese mainland is then under threat, mostly from torrential rainfall, as Nepartak makes landfall on the vulnerable coast of Fujian Province.

    Tropical Depression Southern of Mexico

    in Hurricanes, Cyclones and Extreme weather worldwide

    Posted

    ZCZC MIATWOEP ALL TTAA00 KNHC DDHHMM TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 1100 AM PDT MON JUN 13 2016 For the eastern North Pacific...east of 140 degrees west longitude: 1. An area of low pressure is expected to develop south of the coast of southern Mexico in a couple of days in association with a tropical wave that is currently located near the Gulf of Tehuantepec. Environmental conditions are expected to be conducive for gradual development of this system, and a tropical depression could form later this week while the disturbance moves westward or west-northwestward.

    * Formation chance through 48 hours...low...20 percent
    * Formation chance through 5 days...medium...50 percent

    Graduate programs in Oceanography or Ocean Engineering

    in Spring Weather Discussion

    Posted · Edited by Konstantinos

    What is your opinion about Oceanography or Ocean Engineering graduate studies? I already have a degree in Electrical and Computer Engineering, and now I work as mobile - machine learning developer. But my dream is to deal with Oceans. I want to focus on the Ocean meteorology, Ocean waves, Ocean geography and maybe Naval Engineering. What is your opinion? Do you know any good universities in Europe or North America (especially Canada)? Can you suggest me a few books for introduction?

    So far, I have found this in Canada: http://www.mcgill.ca/gradapplicants/atmospheric-and-oceanic-sciences-0

    Thanks in advance.

    Wet-bulb temperature and health

    in Spring Weather Discussion

    Posted

    The first heat wave is coming in Athens this week so I am wondering about a few things...

    About the degrees of wet bulb temperature, when does body feel hot? When body feels heat wave? What degrees of wet-bulb temperature are dangerous for the health?

    Wiki just says:

    A sustained wet-bulb temperature exceeding 35 Â°C is likely to be fatal even to fit and healthy people, unclothed in the shade next to a fan; at this temperature we switch from cooling the skin (losing heat to the environment), to warming it.

    Thanks in advance...

    Real-time wind gust speed question for newbie

    in Weather stations and equipment

    Posted

    Weather stations do not records gusts, only wind speed. A gust is then calculated after the event as the highest returned speed over a range of data packets from the sensor. Even if the Maplin one above returns data every 48 seconds, it may be actually recording data more often than that (you will have to dig deep into the specs for this) so when it sends a transmission to the console it may be working gust out from the highest speed recorded over several sets of data. However, the frequency of data sets recorded vs. the frequency of data sets transmitted is very different for different weather stations.

    I understood, but why so awful calculations?My Kestrel 4500 NV, updated every second and it shows the real gust.For example it can show current wind speed in 32-second 31 mph, current wind speed in 33-second 31 mph and gust 33 mph, because it felt this, for example, in 32,7 second.
