Am dywydd diddorol Gyfeillion y Gwanwyn!

Wrth edrych trwy ein canlyniadau o 2011 i 2017 (gan ddefnyddio'r siart ar y dde), gallwn weld fod Tachwedd a Rhagfyr 2017 wedi cael tymheredd a glawiad llai na'r cyfartalog, ond oriau o haul uchaf na'r cyfartalog! Drwy gymharu'r data ar gyfer 2017 gyda blynyddoedd blaenorol, gallwn weld cafodd Tachwedd a Rhagfyr 2017 yr oriau o haul trydydd uchaf ers i ni gychwyn ein cofnodion.

Beth am weithio allan eich darlleniadau cyfartalog ar gyfer mis Tachwedd a Rhagfyr a chymharu heu’n hefo’r darlleniadau yn y tabl?

Mae nifer ohonoch wedi rhoi gwybod bod eich planhigion wedi cychwyn tyfu! Ydych chi'n meddwl y bydd y Crocws neu’r Cennin Pedr yn ymddangos yn gyntaf? Beth am edrych drwy’r adroddiad llynedd a chymharu'r dyddiau blodeuo ar gyfer y Crocws a’r Cennin Pedr i'ch helpu penderfynu pa un fydd yn tyfu’n gyntaf?

Rwyf wedi atodi lluniau gan ysgolion a rhannwyd ar Twitter. Plîs rhannwch eich lluniau fel bydda’n gallu dangos nhw ar fy blog nesaf!

Daliwch ati Gyfeillion y Gwanwyn,

Helo Cyfeillion y Gwanwyn,

Heddiw yw’r diwrnod olaf i gasglu darlleniad tywydd cyn Nadolig! Byddwch yn cymryd darlleniad tywydd nesaf yr wythnos o’r 8-12 Ionawr. Wrth gofnodi eich darlleniadau i’r wefan, plîs nodwch ‘dim cofnod’ ar gyfer y dyddiau rydych i fwrdd o’r ysgol.

Does dim rhaid cymryd eich potiau adra dros y gwyliau. Os yw’r potiau mewn lle saf lle byddant ddim yn cael ei effeithio gan y gwynt, bydda nhw’n iawn. Mae'r pridd yn cadw’r bylbiau yn ddwfn yn erbyn y tywydd oer.

Mae’r tywydd wedi bod yn eithaf cynnes am y gaeaf, a bydd o’n ddiddorol i weld yr effaith mae hyn yn cael ar ein bylbiau! Gwelodd Tachwedd 2017 tymereddau ucha a llai o law na flwyddyn ddiwethaf. Ac er ein bod wedi cael ychydig llai o oriau haul na'r llynedd, oedd Tachwedd 2017 dal yr ail mwyaf heulog ers i gofnodion DU cychwyn yn 2012! Os mae’r patrwm yma yn parhau, efallai fyddwn yn weld ein blodau yn gynharach flwyddyn yma!

Mwynhewch eich gwyliau Cyfeillion y Gwanwyn.

Nadolig Llawen a Blwyddyn Newydd Dda,

Athro’r Ardd a Bwlb Bychan

Sylwadau:

Diolch ichi am eich holl sylwadau, cawsom grynodebau tywydd manwl iawn am yr wythnosau diwethaf, ac rydw i'n hynod o falch! Rydym hefyd wedi cael gwybod gan ychydig o ysgolion bod eu planhigion wedi dechrau blaguro! Byddwn yn ddiolchgar pe gallai'r ysgolion hyn rannu lluniau gyda mi cyn ac ar ôl y gwyliau Nadolig, fel y gallwn ni i gyd weld faint maent yn tyfu yn yr amser hwn!

Diolch am eich holl waith caled Cyfeillion y Gwanwyn. Edrychaf ymlaen at barhau eto yn y Flwyddyn Newydd!

Athro'r Ardd

Helo Cyfeillion y Gwanwyn,

Diolch am rannu eich sylwadau gyda'r data tywydd wythnos dwytha. Rwyf wedi atodi rhai yn isod. Mae llawer ohonoch yn ddweud bod y tywydd wedi oeri a bod 'na mwy o law. Mae rhai ohonoch chi hyd yn oed wedi cael eira! Dyma pam dwi am esbonio sut mae meteorolegwyr (gwyddonwyr tywydd) yn mesur eira. 

Mae mesur faint o law sy’n disgyn yn hawdd o’i gymharu â mesur faint o eira sy’n disgyn. Fydd eira ddim yn bihafio! Bydd yn aml yn cael ei chwythu gan y gwynt ac yn lluwchio, sy’n golygu bod yr eira’n ddwfn mewn mannau ond yn llawer llai dafliad carreg i ffwrdd. Oherwydd bod yr eira’n disgyn yn anghyson, bydd y mesuriadau o’r llefydd yma’n anghywir! Dyna pam mae’n rhaid mesur mewn mannau gwastad, agored ymhell o ble fydd eira’n lluwchio. Bydd eira hefyd yn chwarae gemau gyda’r Meteorolegwyr sy’n ceisio ei fesur – bydd yn toddi’n ddŵr, cyn rhewi fel iâ. Felly dyw’r eira sy’n cael ei fesur ddim bob tro yn cyfateb i faint o eira sydd wedi disgyn. Mae eira newydd yn disgyn ar ben hen eira hefyd, ac mae’n anodd dweud faint o eira sydd wedi disgyn o un diwrnod i’r llall. 

Mae’n rhaid i’r meteorolegwyr gofio holl driciau’r eira a meddwl am ffyrdd i ddarganfod faint o eira sydd wedi disgyn. Byddan nhw’n edrych ar gwymp eira (faint o eira sy’n disgyn mewn diwrnod) a dyfnder eira (cyfanswm dyfnder yr eira, hen a newydd). Un ffordd o fesur cwymp eira yw gyda ffon bren. Bydd y meteorolegwr yn gosod y pren mewn lleoliad agored lle na fydd eira’n lluwchio ac yn mesur yr eira bob chwech awr. Drwy glirio’r eira o’r pren ar ôl ei fesur, dim ond eira’r diwrnod hwnnw fydd yn cael ei fesur, a gall y gwyddonydd ddweud faint o eira sydd wedi cwympo ar y diwrnod hwnnw. 

Gallwn ni hefyd fesur eira wedi toddi ar ffurf dŵr. Gallwch chi felly ddefnyddio’ch mesurydd glaw i fesur cwymp eira. Os taw dim ond ychydig o eira sy’n cwympo, bydd yn toddi yn y mesurydd beth bynnag, ond os yw hi’n bwrw’n drwm, ewch â’r mesurydd i mewn ac aros iddo doddi’n ddŵr. Gallwch chi wedyn fesur y dŵr fel rydych chi wedi’i wneud bob wythnos, a’i gofnodi fel glawiad yn eich cofnodion tywydd. 

Os oes eira ar lawr a bod digon o amser i arbrofi, beth am fynd ati i fesur dyfnder yr eira? Y cyfan sydd ei angen arnoch chi yw pren mesur (neu pren eira os ydych chi am siarad fel gwyddonydd gwych!). Gwthiwch y pren i’r eira tan ei fod yn cyffwrdd y ddaear a chofnodi pa mor ddwfn yw’r ddaear fesul milimedr. Rhaid i chi fesur o arwyneb gwastad (fel mainc) mewn lle agored lle nad yw’r eira’n lluwchio. Rhaid i chi gofnodi o leiaf tri mesuriad i gyfrifo dyfnder cyfartalog yr eira lleol. Cyfrifwch y cyfartaledd drwy adio’r cofnodion gwahanol a’u rhannu gyda’r nifer o gofnodion. Os ydw i’n cofnodi tri dyfnder o 7cm, 9cm a 6cm, rhaid i fi adio pob rhif (7 + 9 + 6 = 22) cyn rhannu gyda 3 (22 / 3 = 7.33). Dyfnder cyfartalog yr eira felly yw 7.33cm. 

Mae gorsafoedd tywydd fel y Swyddfa Dywydd (MET Office) wedi troi at dechnoleg i ddyfeisio dulliau newydd o fesur dyfnder eira. Edrychwch ar y llun o un o orsafoedd eira’r Swyddfa Dywydd. Mae nhw’n defnyddio synwyryddion laser i fesur dyfnder yr eira ar yr arwyneb gwastad. Gall meteorolegwyr gasglu data o bob cwr o’r wlad wrth wasgu botwm – llawer haws a mwy dibynadwy nag anfon pobl allan i’r oerfel gyda phren eira! Mae pob un o orsafoedd eira’r Swyddfa Dywydd i’w gweld ar y map – oes un yn agos atoch chi? 

Os yw hi wedi bwrw eira, cofiwch fesur y cwymp gyda’r mesurydd glaw neu’r dyfnder gyda phren eira a nodi’r canlyniadau fel ‘Sylwadau’ wrth uwchlwytho eich cofnodion wythnosol. Bydd yn ddiddorol cymharu dyfnder yr eira â chwymp yr eira yn y mesurydd glaw! 

Daliwch ati Gyfeillion y Gwanwyn, 

Athro’r Ardd

Eich sylwadau o wythnos tri:

Ysgol Y Traeth: Wedi bwrw glaw llawer ac wedi bod yn wyntog ofnadwy.

Athro’r Ardd: Diolch am rannu eich sylwadau tywydd Cyfeillion.

Ysgol Beulah: Mae'n llawer oerach heddiw na oedd e llawer mwy or wythnos.

Athro’r Ardd: Helo, dywedodd ysgolion eraill mai dydd Gwener oedd eu diwrnod oeraf nhw hefyd. Diolch am rannu eich sylwadau tywydd.

Arkholme CE Primary School: This week it has flooded the garden and also the playground. As you can see, there has been quite a lot of rainfall and it has been quite chilly. Lancaster had the most rainfall recorded in one day ever.

Athro’r Ardd: Hi Bulb Buddies, I heard about flooding in your area on the news. I hope the school grounds have drained now and that you are able to play outside again. Keep me updated!

Henllys CIW Primary: On Wednesday actual rainfall 22mm.

Athro’r Ardd: Thank you for the detailed weather report Bulb Buddies.

Canonbie Primary School: It has been a busy week as in rehearsal mode for our school show. It has rained more this week. It has been icy and cold.

Athro’r Ardd: You’re not the only ones to report an increase in rain fall Ysgol Bro Pedr, I’m interested to see if this continues into next week!

Inverkip Primary School: Will our plants grow well with this temperature and rainfall? We think our plants will grow well because they are getting used to a new temperature and are not getting too much rainfall.

Athro’r Ardd: Hi Bulb Buddies, your plants are very sturdy and are nice and snug in the earth. Your temperature and rainfall from this week will be perfect for them, it’s only extreme weather conditions that would prove difficult for them!

St Paul's CE Primary School: Rainy and windy days, with heavy rain 23.11.17 overnight (22.11.17). Frosty on each of the mornings.

Athro’r Ardd:  Thank you for your weather observations Bulb Buddies. I can see that your readings show a much wetter week than in week two.

Darran Park Primary: We have had lots of rain with quite high temperatures except for Friday where the temperature was a lot colder with no rain

Athro’r Ardd:  Thank you for your observations Bulb Buddies. 

Helo Gyfeillion y Gwanwyn, rwyf wedi mwynhau darllen eich sylwadau ac astudio eich data. Rwyf hefyd wedi mwynhau'r lluniau a rannwyd ar Twitter yn dangos rhai ohonoch yn cymryd eich darlleniadau tywydd. Mae'n edrych fel eich bod chi wedi wynebu pob math o dywydd i astudio gwyddoniaeth! Wych!

Mae'r rhan fwyaf ohonoch wedi nodi bod y tywydd yn oerach, ac mae rhai wedi nodi rhew! Beth ydych chi'n meddwl fydd y tywydd yn ei wneud rhwng nawr a’r Nadolig yn eich ardal chi? Ydych chi'n meddwl y byddwch chi’n cael Nadolig gwyn? Edrychwch ar wefan y MET Office i weld a yw meteorolegwyr (gwyddonwyr tywydd) yn meddwl yr un peth â chi.

Eich Sylwadau:

Athro’r Ardd: Hi Bulb Buddies, thank you for sharing your weather observations with me! I hope that you are enjoying the project.

Canonbie Primary School: We really liked this week because everyone had a good time measuring rainfall and temperature. We liked using the correct scales to measure temperature in Degrees Celsius. We made sure that our results were accurate whilst having fun as well! It has been quite cold this week but the afternoons have been brighter-lovely fresh weather. See you next week.

Athro’r Ardd: Hi Bulb Buddies, I’m glad to hear that you are enjoying the project! It sounds as though you are being very thorough in your investigation. Fantastic work!

Carnforth North Road Primary School: It was very muddy but we really enjoyed it.

Athro’r Ardd: I’m not sure if planting your bulbs was muddy, or if it was muddy when you collected your weather readings? I’m sure mud will have added to the fun in both cases!

Waddingham Primary School: This week the whole class read the temperature and rainfall measurements so we knew we were accurate.

Athro’r Ardd: Good work Bulb Buddies, consistency is important to scientific investigations. Keep up the good work!

Inverkip Primary School: Our temperature has been the same all week. We hope this will make our bulbs grow faster.

Athro’r Ardd: That’s very interesting Bulb Buddies. Are you able to check the thermometer in the morning, just to be sure that it is working properly? It’s likely to be colder in the morning than it will be in the afternoon. Why do you think that is?
