Accurate estimate of transpiration is fundamental to develop water-saving management practices and optimize irrigation management. Penman–Monteith (P–M) model based on aerodynamic resistance ( r a ) estimated from heat transfer coefficient method and Perrier logarithm method were used to calculate the hourly and daily grapevine transpiration in solar greenhouse. The results show that the daytime canopy resistance ( r c ) of grapevines was basically maintained between 200 and 250 s m −1 during the two growing seasons. The main convection type in the greenhouse was free convection (68.8–87.5%), and supplemented by mixed convection (12.5–31.3%). The intensity of free convection gradually increased with the growth stage. r a1 and r a2 calculated under the free and mixed convection conditions had no noticeable difference and the variation trend was the same, but both were higher than r a′ calculated by the Perrier logarithmic method. The modified P–M models based on the three aerodynamic resistance methods all overestimated transpiration at the early growth stage and underestimated transpiration at the middle and late growth stages to different degrees. Overall, the P–M model under the three methods could accurately simulate hourly transpiration with a determination coefficient ( R 2 ) and root mean squared error (RSME) greater than 0.89 and 23.4 W m −2 . r a based on the heat transfer coefficient correction improved the accuracy of daily transpiration simulation, and the P–M r a 1 model based on the free convection condition had the highest precision ( R 2  ≥ 0.97, RSME ≤ 17.4 W m −2 ). The P–M model with r a calculated under free convection is recommended to simulate grapevine transpiration in greenhouse in cold regions of Northeast China.
