    Exclamation NASA - Solar Storm Warning

    Researchers say a storm is coming--the most intense solar maximum in fifty years.

    It's official: Solar minimum has arrived. Sunspots have all but vanished. Solar flares are nonexistent. The sun is utterly quiet.

    Like the quiet before a storm.

    Recently researchers announced that a storm is coming--the most intense solar maximum in fifty years. The prediction comes from a team led by Mausumi Dikpati of the National Center for Atmospheric Research (NCAR). "The next sunspot cycle will be 30% to 50% stronger than the previous one," she says. If correct, the years ahead could produce a burst of solar activity second only to the historic Solar Max of 1958.

    That was a solar maximum. The Space Age was just beginning: Sputnik was launched in Oct. 1957 and Explorer 1 (the first US satellite) in Jan. 1958. In 1958 you couldn't tell that a solar storm was underway by looking at the bars on your cell phone; cell phones didn't exist. Even so, people knew something big was happening when Northern Lights were sighted three times in Mexico. A similar maximum now would be noticed by its effect on cell phones, GPS, weather satellites and many other modern technologies.

    Dikpati's prediction is unprecedented. In nearly-two centuries since the 11-year sunspot cycle was discovered, scientists have struggled to predict the size of future maxima--and failed. Solar maxima can be intense, as in 1958, or barely detectable, as in 1805, obeying no obvious pattern.

    The key to the mystery, Dikpati realized years ago, is a conveyor belt on the sun.

    We have something similar here on Earth--the Great Ocean Conveyor Belt, popularized in the sci-fi movie The Day After Tomorrow. It is a network of currents that carry water and heat from ocean to ocean--see the diagram below. In the movie, the Conveyor Belt stopped and threw the world's weather into chaos.

    The sun's conveyor belt is a current, not of water, but of electrically-conducting gas. It flows in a loop from the sun's equator to the poles and back again. Just as the Great Ocean Conveyor Belt controls weather on Earth, this solar conveyor belt controls weather on the sun. Specifically, it controls the sunspot cycle.

    Solar physicist David Hathaway of the National Space Science and Technology Center (NSSTC) explains: "First, remember what sunspots are--tangled knots of magnetism generated by the sun's inner dynamo. A typical sunspot exists for just a few weeks. Then it decays, leaving behind a 'corpse' of weak magnetic fields."

    Enter the conveyor belt.

    "The top of the conveyor belt skims the surface of the sun, sweeping up the magnetic fields of old, dead sunspots. The 'corpses' are dragged down at the poles to a depth of 200,000 km where the sun's magnetic dynamo can amplify them. Once the corpses (magnetic knots) are reincarnated (amplified), they become buoyant and float back to the surface." Presto--new sunspots!

    All this happens with massive slowness. "It takes about 40 years for the belt to complete one loop," says Hathaway. The speed varies "anywhere from a 50-year pace (slow) to a 30-year pace (fast)."

    When the belt is turning "fast," it means that lots of magnetic fields are being swept up, and that a future sunspot cycle is going to be intense. This is a basis for forecasting: "The belt was turning fast in 1986-1996," says Hathaway. "Old magnetic fields swept up then should re-appear as big sunspots in 2010-2011."

    Like most experts in the field, Hathaway has confidence in the conveyor belt model and agrees with Dikpati that the next solar maximum should be a doozy. But he disagrees with one point. Dikpati's forecast puts Solar Max at 2012. Hathaway believes it will arrive sooner, in 2010 or 2011.

    "History shows that big sunspot cycles 'ramp up' faster than small ones," he says. "I expect to see the first sunspots of the next cycle appear in late 2006 or 2007--and Solar Max to be underway by 2010 or 2011."

    olar Storm Warning
    03.15.06 03.15.06
    Researchers say a storm is coming--the most intense solar maximum in fifty years. Peneliti mengatakan badai yang akan datang - yang paling intens solar maksimal dalam lima puluh tahun.

    It's official: Solar minimum has arrived . It's resmi: Solar minimum telah tiba. Sunspots have all but vanished. Sunspots ada tetapi semua hilang. Solar flares are nonexistent. Solar flares yang nonexistent. The sun is utterly quiet. Matahari sama sekali sepi.

    Like the quiet before a storm. Seperti yang tenang sebelum badai.

    Recently researchers announced that a storm is coming--the most intense solar maximum in fifty years. Peneliti baru-baru ini mengumumkan bahwa badai yang akan datang - yang paling intens solar maksimal dalam lima puluh tahun. The prediction comes from a team led by Mausumi Dikpati of the National Center for Atmospheric Research (NCAR). Prediksi yang datang dari sebuah tim yang dipimpin oleh Mausumi Dikpati dari National Center for Atmospheric Research (NCAR). "The next sunspot cycle will be 30% to 50% stronger than the previous one," she says. "Siklus berikutnya bintik pd matahari akan 30% menjadi 50% lebih kuat dibandingkan dengan sebelumnya," ujarnya. If correct, the years ahead could produce a burst of solar activity second only to the historic Solar Max of 1958. Jika benar, maka tahun depan bisa menghasilkan solar burst dari aktivitas kedua hanya dengan Solar Max bersejarah dari 1958.

    That was a solar maximum. Itu adalah matahari maksimum. The Space Age was just beginning: Sputnik was launched in Oct. 1957 and Explorer 1 (the first US satellite) in Jan. 1958. Space Umur itu hanya awal: Sputnik diluncurkan pada tahun 1957 dan Explorer Oct 1 (pertama US satelit) di Jan 1958. In 1958 you couldn't tell that a solar storm was underway by looking at the bars on your cell phone; cell phones didn't exist. Pada tahun 1958 Anda tidak dapat kirim badai solar yang telah berlangsung dengan melihat bar di ponsel Anda, ponsel tidak ada. Even so, people knew something big was happening when Northern Lights were sighted three times in Mexico. Meskipun demikian, orang tahu sesuatu yang besar yang terjadi ketika Northern Lights adalah mata tiga kali di Meksiko. A similar maximum now would be noticed by its effect on cell phones, GPS, weather satellites and many other modern technologies. Maksimum yang sama sekarang akan melihat dengan efek pada ponsel, GPS, satelit cuaca, dan banyak lainnya teknologi modern.

    Dikpati's prediction is unprecedented. Dikpati dari perkiraan yang belum pernah terjadi sebelumnya. In nearly-two centuries since the 11-year sunspot cycle was discovered, scientists have struggled to predict the size of future maxima--and failed. Dalam hampir dua abad sejak tahun 11-bintik pd matahari siklus telah ditemukan, para ilmuwan telah berjuang untuk memprediksi ukuran depan maxima - dan gagal. Solar maxima can be intense, as in 1958, or barely detectable, as in 1805, obeying no obvious pattern. Solar maxima dapat intens, seperti pada 1958, atau hampir detectable, seperti di 1805, menurut pola tidak jelas.

    The key to the mystery, Dikpati realized years ago, is a conveyor belt on the sun. Kunci misteri, Dikpati realisasi tahun lalu, merupakan sebuah ban berjalan di bawah sinar matahari.

    We have something similar here on Earth--the Great Ocean Conveyor Belt, popularized in the sci-fi movie The Day After Tomorrow . Kami punya sesuatu yang serupa di sini di dunia - Great Ocean Belt conveyor, populer di sci-fi film The Day After Tomorrow. It is a network of currents that carry water and heat from ocean to ocean--see the diagram below. Ini adalah jaringan yang membawa arus air panas dan dari laut ke laut - lihat diagram di bawah ini. In the movie, the Conveyor Belt stopped and threw the world's weather into chaos. In the movie, the ban berjalan berhenti dan melemparkan cuaca di dunia ke dalam kekacauan.

    The sun's conveyor belt is a current, not of water, but of electrically-conducting gas. Matahari dari ban berjalan adalah saat ini, bukan air, tetapi melakukan elektrik-gas. It flows in a loop from the sun's equator to the poles and back again. Ia mengalir dalam satu lingkaran dari matahari dari khatulistiwa ke tiang dan kembali lagi. Just as the Great Ocean Conveyor Belt controls weather on Earth, this solar conveyor belt controls weather on the sun. Sama seperti Great Ocean Belt conveyor kontrol cuaca di Bumi, ini solar conveyor belt kontrol cuaca pada Minggu. Specifically, it controls the sunspot cycle. Khususnya, ia mengendalikan siklus bintik pd matahari.

    Solar physicist David Hathaway of the National Space Science and Technology Center (NSSTC) explains: "First, remember what sunspots are--tangled knots of magnetism generated by the sun's inner dynamo. A typical sunspot exists for just a few weeks. Then it decays, leaving behind a 'corpse' of weak magnetic fields." Solar fisika David Hathaway dari Ruang Angkasa Nasional Sains dan Teknologi (Pusat NSSTC) menjelaskan: "Pertama, ingat apa yang sunspots - masai knots daya yang dihasilkan oleh matahari dari batin dinamo. J khas ada bintik pd matahari hanya untuk beberapa minggu. Kemudian decays , sehingga di belakang 'mayat' medan magnet yang lemah. "

    Enter the conveyor belt. Masukkan ban berjalan.

    "The top of the conveyor belt skims the surface of the sun, sweeping up the magnetic fields of old, dead sunspots. The 'corpses' are dragged down at the poles to a depth of 200,000 km where the sun's magnetic dynamo can amplify them. Once the corpses (magnetic knots) are reincarnated (amplified), they become buoyant and float back to the surface." "Di atas ban berjalan skims permukaan matahari, pemandangan yang magnetis bidang lama, mati sunspots. The 'corpses' telah menyeret di bawah tiang ke kedalaman 200.000 km dimana matahari dari magnetis dinamo dapat memperkuat mereka. Setelah corpses (magnetis knot) adalah reincarnated (amplified), mereka menjadi ringan dan hanyut kembali ke permukaan. " Presto--new sunspots! Presto - sunspots baru!

    All this happens with massive slowness. Semua hal ini terjadi dengan besar kelambatan. "It takes about 40 years for the belt to complete one loop," says Hathaway. "Waktu tempuh kurang lebih 40 tahun untuk menyelesaikan satu sabuk lingkaran," kata Hathaway. The speed varies "anywhere from a 50-year pace (slow) to a 30-year pace (fast)." Kecepatan bervariasi "di mana saja dari 50-tahun kecepatan (lambat) ke-30 tahun kecepatan (cepat)."

    When the belt is turning "fast," it means that lots of magnetic fields are being swept up, and that a future sunspot cycle is going to be intense. Ketika sabuk itu berpaling "cepat", berarti banyak medan magnet sedang swept atas, dan bahwa masa depan adalah siklus bintik pd matahari akan intens. This is a basis for forecasting: "The belt was turning fast in 1986-1996," says Hathaway. Ini adalah dasar untuk meramalkan: "ikat pinggang yang telah beralih cepat di 1986-1996," kata Hathaway. "Old magnetic fields swept up then should re-appear as big sunspots in 2010-2011." "Lama medan magnet swept atas maka harus kembali muncul sebagai sunspots besar di 2010-2011."

    Like most experts in the field, Hathaway has confidence in the conveyor belt model and agrees with Dikpati that the next solar maximum should be a doozy. Seperti kebanyakan para ahli di bidangnya, memiliki keyakinan Hathaway di ban berjalan sesuai dengan model dan Dikpati yang selanjutnya solar maksimum harus doozy. But he disagrees with one point. Tetapi ia tidak dengan satu titik. Dikpati's forecast puts Solar Max at 2012. Dikpati dari ramalan puts Solar Max di 2012. Hathaway believes it will arrive sooner, in 2010 or 2011. Hathaway percaya akan tiba cepat, pada tahun 2010 atau 2011.

    "History shows that big sunspot cycles 'ramp up' faster than small ones," he says. "Sejarah menunjukkan bahwa siklus bintik pd matahari besar 'jalan atas' lebih cepat dari yang kecil," ujarnya. "I expect to see the first sunspots of the next cycle appear in late 2006 or 2007--and Solar Max to be underway by 2010 or 2011." "Saya berharap untuk melihat sunspots pertama dari siklus berikutnya muncul pada akhir 2006 atau 2007 - dan Solar Max yang akan dilaksanakan pada tahun 2010 atau 2011."

    Tidak disebutkan kiamat, akan tetapi kerusakan yang ditimbulkan akan cukup dasyat menurut perhitungan para ahli NASA.
