Temperature variability in northern Iran during the past 700 years

Strong link between large tropical volcanic eruptions and severe droughts prior to monsoon in the central Himalayas revealed by tree-ring records

“…Our findings were supported by other work in the central Himalayas where the growth of Abies spectabilis, Pinus roxburghii, Pinus wallichiana and Picea smithiana was also limited by pre-monsoon precipitation [14][15][16]. It seems likely that these results differ from studies in cold biomes in the Northern Hemisphere e.g., [17][18][19] because of the reduction of precipitation in higher elevation in the central Himalayas and that most of our sites are in rain shadow locations. Further, work in high elevation mountains in the American west indicates that upper timberline trees in some locations were more limited by moisture than cool temperatures [20,21].…”

Moisture-Limited Tree Growth for a Subtropical Himalayan Conifer Forest in Western Nepal

“…As shown in a recent study, low winter and spring precipitation can cause a delay of the initiation of xylogenesis and contribute to the occurrence of the locally missing rings in years with extremely dry springs [51]. Ongoing warming temperatures could not only cause soil moisture deficiency but also amplify temperature-induced drought stress, thereby limiting tree growth and posing a risk of die-off under a warming climate [52][53][54][55][56].…”

Growth response of Abies spectabilis to climate along an elevation gradient of the Manang valley in the central Himalayas

“…Likewise, site-specific climate data could better explain such climate-growth relationships. Generally, temperature is a growth limiting factor for trees at higher elevations (Liu et al 2005;Fan et al 2008;Affolter et al 2010;Bayramzadeh et al 2018;Yu and Liu 2018). In the central Himalayas, spring precipitation is considered to be a driving factor for tree growth, in particular in high-elevation forests (Dawadi et al 2013;Liang et al 2014Liang et al , 2019Panthi et al 2017;Tiwari et al 2017), as well as in subtropical forests (Sigdel et al 2018a).…”
