Nor­austan stormur Ý desember - A northeast storm in December

Ůa­ hefur hent ˇ■arflega oft a­ undirrita­ur er grasekkill einn heima hjß sÚr ■egar ˇve­ur skellur ß. Ůannig var ■etta Ý kv÷ld.

Hljˇ­nemar voru settir ˙t ß svalir sem vita mˇt su­vestri til ■ess a­ fanga gauragang vindsins. Ver­ur ■a­ hljˇ­rit birt sÝ­ar.

┴ g÷ngum fj÷lbřlish˙ssins var talsver­ur hßva­i og undirtˇk Ý verstu vindhvi­unum.

Hljˇ­rita­ var me­ Olympus LS-11 og Rode NT4.

Seinna hljˇ­riti­ er af sv÷lum h˙ssins. Ůar var hljˇ­rita­ me­ Nagra Ares BB+ og tveimur Sennheiser ME-62 Ý AB-uppsetningu.

MŠlt er me­ gˇ­um heyrnartˇlum og ekki of miklum styrk.

Vindur Ý h˙sasundi - The wind between two houses

Ůa­ sem af er sumri hefur veri­ fremur sˇlrÝkt, vindasamt og svalt. ═ morgun ßtta­i Úg mig ß skemmtilegum hljˇ­um sem nor­anvindurinn mynda­i ß sv÷lunum ß Tjarnarbˇli 14 sem vÝsa Ý su­vestur. Vegna nřrrar byggingar sem er vestan vi­ Tjarnarbˇl 14 ■řtur ÷­ruvÝsi Ý vindinum en ß­ur.
Notast var vi­ einfaldan b˙na­, Olympus LS-11 og skori­ af 100 ri­um. Hljˇ­riti­ er Ý fullum gŠ­um, 24 bitum og er ■vÝ ni­urhali­ fremur hŠgt.
MŠlt er me­ gˇ­um heyrnartˇlum.

In English.
This summer has up to now been sunny, cold and windy. I noticed that the wind produced some special sounds on my balkony facing southwest. The northern wind now has to go through between our hous and the new one close to the west.
A simple geer was used, Olympus-11.
The recording is in 24 bits and the download can therefore be a little slow.
Good headphones are recommended.

Ofvi­ri­ 14. mars - The Tempest on March 14

Enn eitt ˇve­ri­ geisa­i ß sunnanver­u landinu a­ morgni 14. Mars 2015. ┴ KeflavÝkurflugvelli var vindhra­inn um 30 m/sek kl. 10:00 og mß gera rß­ fyrir a­ hann hafi veri­ svipa­ur hÚr ß Seltjarnarnesi.

TŠkifŠri­ var nota­ og ˇsk÷pin hljˇ­ritu­ Ý stofunni ß heimili okkar sem veit mˇt su­vestri. Nota­ur var Nagra Ares BB+ hljˇ­riti ßsamt tveimur R°de NT1-A hljˇ­nemum Ý AB-uppsetningu.

Hljˇ­ritun hˇfst kl. 09:45.

Upprunalega hljˇ­riti­ er 24 bita og 48 kÝlˇri­. Ekkert hefur veri­ skori­ af lßgtÝ­ni hljˇ­ritsins, en hin dj˙pu hljˇ­, sem steinsteypt h˙s gefa jafnan frß sÚr Ý ofvi­ri, heyr­ust vel og ■vÝ ˇe­lilegt a­ breyta ■eim. Eindregi­ er mŠlt me­ gˇ­um heyrnartˇlum.

In English

Yet another tempest raged in Southwest Iceland in the morning of March 14 ths year. The wind speed was about 30 m/sek.

A recording was made in our living room facing south-west.

A Nagra Ares BB+ was used together with 2 R°de NT1-A microphones in an AB-setup. The original recording is in 48 kHz and 24 bits.

The lower frequencies have not been cut off. Therefore the deep rumbling sounds of the hous are easily heard. We heard them ourselves and therefor I thought it unnecessary to edit the sound.

The recording starts at 09:45.

Good headphones are recommended.

Vindur blŠs um vetrarnßtt - The Wind in the Winter Night

A­ kv÷ldi 6. desember 2014 kom Úg fyrir tveimur Sennheiser ME-62 hljˇ­nemum utan vi­ svalirnar ß 3. hŠ­ a­ Tjarnarbˇli 14. Voru ■eir Ý AB-uppsetningu me­ 30 cm bili og ■aktir lo­feldi frß rycote.

Um kl. 4:25 var vindur um 6-10 m/sek a­ nor­austan. Ătlunin haf­i veri­ a­ fanga ■ungan ni­ hafsins Ý fjarska en Ý sta­inn yfirgnŠf­i vifta Ý nřbyggingu nßtt˙ruhljˇ­in. Ef grannt er eftir hlusta­ heyrist vindurinn ■yrla upp snjˇkornum, ßlftir flj˙ga hjß lengst Ý vestri og alls kyns skr÷lt Ý nřbyggingunni.

Eindregi­ er mŠlt me­ gˇ­um heyrnartˇlum og athyglin ■arf a­ vera ˇskert.

IN ENGLISH

In the evening on December 6 2014 I placed 2 Sennheiser ME-62 mics outside the balcon on our flat in Seltjarnarnes, Iceland, in an AB-setup with 30 mm spacing. They were covered with a fur from Rycote.

At 4:25 in the morning the wind had started blowing from the north-east. Instead of the deep sound of the ocean som 1 km away the sound of a fan in a nearby house under construction was overwhelming.

If the listener uses all his/her attention the wind can be heard whirling some snowflakes around and swans flying to the south in the far west. All kinds of sounds from the building is also here and there.

Good headphones are strongly recommended.

Ofvi­ri Ý desember - A Tempest in December

A­ kv÷ldi sunnudagsins 1. desember gekk ofvi­ri yfir vestanvert landi­. ┴ KeflavÝk var­ ve­urhŠ­in allt a­ 30 m. Mß ■vÝ b˙ast vi­ a­ ve­urhŠ­in hafi veri­ svipu­ ß Seltjarnarnesi, en ve­urfari ■ar svipar mj÷g til KeflavÝkur.

╔g kom fyrir tveimur R°de NT1-A hljˇ­nemum Ý AB-uppsetningu me­ um 30 cm millibili ß bor­stofubor­inu u.■.b. 2 m frß gluggunum. Athyglisvert er a­ heyra hina dj˙pu undirtˇna h˙ssins sem undirleik vindsins og řmissa smßhluta sem reyna a­ rÝfa sig lausa. Ůessar 11 mÝn˙tur gefa ßgŠta mynd af ■vÝ hvernig er a­ vera einn heima Ý slÝku ve­ri.

In English

In the evening of December 1, 2014, we had a tempest from southwest in Southern Iceland. At Keflavik Airport the strongest blasts were at least 30 m/sec (108 km per hour). The weather is quite similar where I am living at Seltjarnarnes.

I placed 2 R°de NT1-A microphones in an AB-array with 30 cm spacing in the livingroom aproximately 2 m from the windows. It is quite interesting to sense the deep roaring of the house as an accompaniment to the wind, pressing through and some objects outside trying to leave the balcony. This recording describes what it is like staying alone at home as the tempest is raging outside.

Good headphones are strongly recommended.

Raforkuvindmyllur - Wind Turbines

Hljˇ­i­ Ý einni vindmyllu er notalegt. En hver ver­a ßhrifin er 80 myllur ver­a settar upp? Ljˇsmynd: ElÝn ┴rnadˇttirNor­an vi­ B˙rfellsvirkjun eru tvŠr vindmyllur. Ůegar okkur bar a­ gar­i 26. ■essa mßna­ar var vindur um 5-10 m/sek og raforkuframlei­sla einungis um 75 kW. Nokkru nor­ar er ÷nnur vindmylla, sem ekki var opin, en ■ar sem enginn var vi­ hana var h˙n valin til hljˇ­ritunar.

Um ■a­ leyti sem hljˇ­ritun hˇfst jˇkst vindurinn nokku­. Ůa­ mß heyra ß hljˇ­ritinu hvernig hljˇ­i­ breytist me­ mismunandi vindstyrk.

Eindregi­ er mŠlt me­ gˇ­um heyrnartˇlum.


┴ sÝ­u landsvirkjunar segir m.a.:

Vindmyllurnar eru hvor um sig 900 kW og samanl÷g­ raforkuframlei­sla ■eirra er ߊetlu­ um 5,4 GWst ß ßri. Ůa­ myndi nŠgja til a­ sjß um 1.200 heimilum fyrir rafmagni til daglegra nota.

Loki­ var vi­ uppsetningu vindmyllanna Ý desember 2012 og ß nŠstu misserum safnast upplřsingar um ■a­ hvort m÷gulegt sÚ a­ breyta Ýslenska rokinu Ý ver­mŠta au­lind. Rannsˇknirnar sn˙ast ekki sÝst um rekstur vindmylla vi­ sÚrÝslenskar a­stŠ­ur, Ýsingu, skafrenning, ÷sku- og sandfok. Ef vel gengur er markmi­i­ a­ vindorkuframlei­sla ver­i Ý framtÝ­inni mikilvŠg vi­bˇt vi­ framlei­slu raforku me­ vatnsafli og jar­varma.

Vindmyllurnar tvŠr ß Hafinu eru framleiddar af ■řska fyrirtŠkinu Enercon, sem sÚrhŠfir sig Ý framlei­slu vindmylla til nota ß landi. Um 60% vindmylla Ý Ůřskalandi eru frß Enercon og um 7% vindmylla Ý heiminum.

Turninn er 55 metra hßr og hver spa­i 22 metrar ß lengd. Ůegar spa­arnir eru Ý efstu st÷­u er heildarhŠ­ myllunnar 77 metrar. Frekari upplřsingar eru ß

Will the wind finally do some good?

In December, Landsvirkjun erected two wind turbines, in an area known as Hafi­, within the construction area of B˙rfell Power Station, in the south of Iceland. The turbines have a total of 2 MW of installed power. The project is part of Landsvirkjunĺs research and development project on the advantageous of wind power in Iceland. There are a number of areas in Iceland that show great potential for the successful utilisation of wind energy.

The wind turbines each have a 900 kW capacity and together their generating capacity could be up to 5.4 GWh per year. The masts is 55 metres heigh and each spade measures 22 metres in length. When the spades are at their highest position the unit is 77 metres of height. Wind turbines developed for further energy production will in all likelihood be larger than the most powerful turbines presently operating in Iceland today, reaching 7.5MW.


When we were there on July 26 the wind was only 5-10 mYsec and the average power only about 75kW for each turbine. We went to the turbine further north as there were no tourists. There we captured the sound. It can be heard during the recording that the sound of the spades changes according to the wind.

Good headphones recommended.
