<prompt> 99 iri muMBH99 inoreva chii? Tichifunga nezvemubvunzo wapfuura, nyora mashoko akapoteredza mhinduro yacho. Inogona kuva mitsara 1 - 20. Mashoko akapoteredza:  <response>: Mushumo wechitatu wekuongorora TAR wakaratidza girafu rakanyorwa kuti Millennial Northern Hemisphere temperature reconstruction zvichibva pane rimwe pepa ra1999 rakanyorwa naMichael E. Mann, Raymond S. Bradley naMalcolm K. Hughes MBH99, iro rakanzi girafu rebhora rehockey. Girafu iyi yakawedzera girafu yakafanana iri muFigure 3.20 kubva kuIPCC Second Assessment Report ya1995, uye yakasiyana nechirongwa chiri mumushumo wekutanga wekuongorora waishaya mayuniti ekutonhora, asi yaiita kunge inoratidza misiyano yakakura yetembiricha yepasi rose mumakore 1000 apfuura, uye tembiricha dzakakwirira panguva yeMedieval Warm Period kupfuura pakati pezana ramakore rechi20. Chirongwa chacho chakanga chisiri chinyorwa chaicho chedata, uye chaive chakavakirwa pachiratidziro chematembiricha muCentral England, netembiricha dzakawedzera pahwaro hweuchapupu hwezvinyorwa zveminda yemizambiringa yeMiddle Ages muEngland. Kunyange nokuwedzera uku, kupisa kwakanyanya kwakaratidzwa kweMedieval Warm Period hakuna kusvika tembiricha dzakanyorwa nechepakati peEngland muna 2007. Kuwana kweMBH99 kwakatsigirwa nekudzokorora kwakataurwa naJones et al. 1998, Pollack, Huang Shen 1998, Crowley Lowery 2000 uye Briffa 2000, vachishandisa data dzakasiyana uye nzira.
