To address this paucity of research, we investigate the effects of feedback from CO outflow candidates on their parent clouds over ~110deg^2^ toward the W3/4/5 complex and its surroundings. Our search identified 265 ^13^CO clouds with radii being ~0.04-17.12pc. We estimate the turbulent support and potential disruptive effect of the outflow activities through analyzing physical properties of outflow candidates and their host clouds in terms of turbulence and gravitational binding energy. We find that (1) clouds of larger size might be less affected by feedback; (2) the possible scale break is >~4.7pc for both turbulent support and potential disruptive effect; (3) if outflows couple to dense gas where stars are forming, for clouds in the Perseus arm, a scale <~0.2-0.4pc is sufficient for the energy and momentum injected by outflow activity to maintain turbulence, while for clouds in the Local arm, the scale is <~0.1-0.2pc; and (4) for clouds in the Perseus arm, a scale <~0.3-1.0pc is needed for outflow activity to potentially disperse material away from the natal clouds, while for clouds in the Local arm, the scale is <~0.2-0.6pc. The strength of outflow activity may affect the values in points 3 and 4. Finally, we find that outflow feedback probably possesses the power to alter the line width-size relation.2020ApJS..251...26Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/251/26CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/64 : Westerhout's Catalogue of 82 Discrete Sources (Westerhout 1958)J/ApJS/181/321 : Properties of Spitzer c2d dark clouds (Evans+, 2009)J/A+A/499/175 : ^12^CO(2-1) map of NGC 2264-C (Maury+, 2009)J/ApJS/219/20 : Outflows and bubbles in Taurus (Li+, 2015)J/ApJS/242/19 : CO outflow candidates toward W3/4/5 complex (Li+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/251/26https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/251/26http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/251/26https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/251/26https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/251/26http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/251/26GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/251/26/table1 (Correlation among clouds and outflow candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/251/26/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/251/26/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/251/26/table1?GETtext/xml+votable180.050000true26.3085857.64980.0055555555555555565/818 819 822 823 825 826 827 828 901 903 6/3223 3228 3229 3247 3253 3255 3258 3259 3261 3262 3263 3266 3271 3297 3298 3299 3316 3318 3319 3320 3322 3324 3595 3597 3600 3602 3603 3609 3610 3611 3636 3637 3648 3649 3650 3652 3653 3654 3656 3657 3658 3663 3664 3666 3672 3674 3680 3681 3684 3685https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/251/26?format=asciiRadiodefaultJ/ApJS/251/26/table2Global physical properties of the cloudsMcloud[0.1/44942.5] Mass of cloudsolMassphys.massfloatrecnoRecord number assigned by the VizieR team.
