python小波分析海温数据的时频域分解小波分析附源码

  今天想搞一个时频分析,这个东西自己没有写过代码,用过别人的代码,但不知道怎么操作。百度一翻,得到一个现成的例子,又在CSDN上有人写了一段类似的代码,效果图一致,是一个开源的github上的代码。下面把开源的代码转发一下,希望对大家有帮助。

  作者分别写了Python版、matlab版、Fortran版的代码,这里只转一下Python代码。作者对代码做了详细的注释,有需要的自己看注释吧。代码包含两部分:waveletAnalysis。pyimportmatplotlib。pylabaspltimportmatplotlib。tickerastickerfrommatplotlib。gridspecimportGridSpecimportnumpyasnpfrommpltoolkits。axesgrid1importmakeaxeslocatablefromwaveletFunctionsimportwavesignif,waveletauthorEvgeniyaPredybayloWAVETESTExamplePythonscriptforWAVELET,usingNINO3SSTdatasetSeehttp:paos。colorado。eduresearchwaveletsTheMatlabcodewrittenJanuary1998byC。TorrencemodifiedtoPythonbyEvgeniyaPredybaylo,December2014ModifiedOct1999,changedGlobalWaveletSpectrum(GWS)tobesideways,changedalllogtolog2,changedlogarithmicaxisonGWStoanormalaxis。READTHEDATAsstnp。loadtxt(sstnino3。dat)inputSSTtimeseriessstsstnp。mean(sst)variancenp。std(sst,ddof1)2print(variance,variance)COMPUTATIONSTARTSHEREnormalizebystandarddeviation(notnecessary,butmakesiteasiertocomparewithplotonInteractiveWaveletpage,athttp:paos。colorado。eduresearchwaveletsplotif0:variance1。0sstsstnp。std(sst,ddof1)nlen(sst)dt0。25timenp。arange(len(sst))dt1871。0constructtimearrayxlim(〔1870,2000〕)plottingrangepad1padthetimeserieswithzeroes(recommended)dj0。25thiswilldo4suboctavesperoctaves02dtthissaysstartatascaleof6monthsj17djthissaysdo7powersoftwowithdjsuboctaveseachlag10。72lag1autocorrelationforrednoisebackgroundprint(lag1,lag1)motherMORLETWavelettransform:wave,period,scale,coiwavelet(sst,dt,pad,dj,s0,j1,mother)power(np。abs(wave))2computewaveletpowerspectrumglobalws(np。sum(power,axis1)n)timeaverageoveralltimesSignificancelevels:signifwavesignif((〔variance〕),dtdt,sigtest0,scalescale,lag1lag1,mothermother)expandsignif(J1)x(N)arraysig95signif〔:,np。newaxis〕。dot(np。ones(n)〔np。newaxis,:〕)sig95powersig95whereratio1,powerissignificantGlobalwaveletspectrumsignificancelevels:dofnscalethescalecorrectsforpaddingatedgesglobalsignifwavesignif(variance,dtdt,scalescale,sigtest1,lag1lag1,dofdof,mothermother)ScaleaveragebetweenElNinoperiodsof28yearsavgnp。logicaland(scale2,scale8)Cdelta0。776thisisfortheMORLETwaveletexpandscale(J1)x(N)arrayscaleavgscale〔:,np。newaxis〕。dot(np。ones(n)〔np。newaxis,:〕)scaleavgpowerscaleavg〔Eqn(24)〕scaleavgdjdtCdeltasum(scaleavg〔avg,:〕)〔Eqn(24)〕scaleavgsignifwavesignif(variance,dtdt,scalescale,sigtest2,lag1lag1,dof(〔2,7。9〕),mothermother)PlottingPlottimeseriesfigplt。figure(figsize(9,10))gsGridSpec(3,4,hspace0。4,wspace0。75)plt。subplotsadjust(left0。1,bottom0。05,right0。9,top0。95,wspace0,hspace0)plt。subplot(gs〔0,0:3〕)plt。plot(time,sst,k)plt。xlim(xlim〔:〕)plt。xlabel(Time(year))plt。ylabel(NINO3SST(C))plt。title(a)NINO3SeaSurfaceTemperature(seasonal))plt。text(time〔1〕35,0。5,WaveletAnalysisC。TorrenceG。P。Compohttp:paos。colorado。eduresearchwavelets,horizontalalignmentcenter,verticalalignmentcenter)Contourplotwaveletpowerspectrumplt3plt。subplot(3,1,2)plt3plt。subplot(gs〔1,0:3〕)levels〔0,0。5,1,2,4,999〕orusecontourCSplt。contourf(time,period,power,len(levels))implt。contourf(CS,levelslevels,colors〔white,bisque,orange,orangered,darkred〕)plt。xlabel(Time(year))plt。ylabel(Period(years))plt。title(b)WaveletPowerSpectrum(contoursat0。5,1,2,4C2))plt。xlim(xlim〔:〕)95significancecontour,levelsat99(fake)and1(95signif)plt。contour(time,period,sig95,〔99,1〕,colorsk)coneofinfluence,anythingbelowisdubiousplt。fillbetween(time,coi0period〔1〕,coi,facecolornone,edgecolor00000040,hatchx)plt。plot(time,coi,k)formatyscaleplt3。setyscale(log,base2,subsNone)plt。ylim(〔np。min(period),np。max(period)〕)axplt。gca()。yaxisax。setmajorformatter(ticker。ScalarFormatter())plt3。ticklabelformat(axisy,styleplain)plt3。invertyaxis()setupthesizeandlocationofthecolorbarpositionfig。addaxes(〔0。5,0。36,0。2,0。01〕)plt。colorbar(im,caxposition,orientationhorizontal),fraction0。05,pad0。5)plt。subplotsadjust(right0。7,top0。9)Plotglobalwaveletspectrumplt4plt。subplot(gs〔1,1〕)plt。plot(globalws,period)plt。plot(globalsignif,period,)plt。xlabel(Power(C2))plt。title(c)GlobalWaveletSpectrum)plt。xlim(〔0,1。25np。max(globalws)〕)formatyscaleplt4。setyscale(log,base2,subsNone)plt。ylim(〔np。min(period),np。max(period)〕)axplt。gca()。yaxisax。setmajorformatter(ticker。ScalarFormatter())plt4。ticklabelformat(axisy,styleplain)plt4。invertyaxis()Plot28yrscaleaveragetimeseriesplt。subplot(gs〔2,0:3〕)plt。plot(time,scaleavg,k)plt。xlim(xlim〔:〕)plt。xlabel(Time(year))plt。ylabel(Avgvariance(C2))plt。title(d)28yrScaleaverageTimeSeries)plt。plot(xlim,scaleavgsignif〔0,0〕,)plt。savefig(。wavelet。png,dpi300)plt。show()waveletFunctions。pyCopyright(C)19952021,ChristopherTorrenceandGilbertP。CompoPythonversionofthecodeiswrittenbyEvgeniyaPredybayloin2014editedbyMichaelvonPapen(FZJuelich,INM6),2018,toincludeanalysisatarbitraryfrequenciesThissoftwaremaybeused,copied,orredistributedaslongasitisnotsoldandthiscopyrightnoticeisreproducedoneachcopymade。Thisroutineisprovidedasiswithoutanyexpressorimpliedwarrantieswhatsoever。Notice:Pleaseacknowledgetheuseoftheabovesoftwareinanypublications:WaveletsoftwarewasprovidedbyC。TorrenceandG。Compo,andisavailableatURL:http:paos。colorado。eduresearchwavelets。Reference:Torrence,C。andG。P。Compo,1998:APracticalGuidetoWaveletAnalysis。IBull。Amer。Meteor。Soc。I,79,6178。Pleasesenda
