Weather extreme could be any weather parameter be it rainfall or temperature that lies outside a locale's normal range of weather intensity. The negative or adverse impact of extreme weather events could be significant whether directly or indirectly inducing stress on plant growth and performance. Enlisting extreme weather events is highly useful to ascertain their occurrence and probable impact in future. The highest single day rainfall (amount of rainfall received in 24 hours' time) was as high as 381.7 mm at Dharamshala in district Kangra, while the other stations in Himachal Pradesh received the lower single day rainfall. The longest dry spells were more frequent with higher variation during October to December which coincided with sowing of the rabi crops than March to May corresponding to grain filling and maturity of the rabi crops and flowering and fruit development stage in mango, apple and stone fruits. In the recent past, the highest recorded maximum temperature was 48.5°C at Dhaulakuan, district Sirmaur while the lowest minimum temperature was -9°C at Salooni, district Chamba. There was decline in number of cold waves, severe cold waves and total number of days with minimum temperature below normal. The occurrence of extreme weather events showed no pattern or periodicity but they continued to affect sowing, flowering, fruit development and maturity in field/ horticultural crops in the state.

Abstract


Weather extreme could be any weather parameter be it rainfall or temperature that lies outside a locale's normal range of weather intensity. The negative or adverse impact of extreme weather events could be significant whether directly or indirectly inducing stress on plant growth and performance. Enlisting extreme weather events is highly useful to ascertain their occurrence and probable impact in future. The highest single day rainfall (amount of rainfall received in 24 hours' time) was as high as 381.7 mm at Dharamshala in district Kangra, while the other stations in Himachal Pradesh received the lower single day rainfall. The longest dry spells were more frequent with higher variation during October to December which coincided with sowing of the rabi crops than March to May corresponding to grain filling and maturity of the rabi crops and flowering and fruit development stage in mango, apple and stone fruits. In the recent past, the highest recorded maximum temperature was 48.5°C at Dhaulakuan, district Sirmaur while the lowest minimum temperature was -9°C at Salooni, district Chamba. There was decline in number of cold waves, severe cold waves and total number of days with minimum temperature below normal. The occurrence of extreme weather events showed no pattern or periodicity but they continued to affect sowing, flowering, fruit development and maturity in field/ horticultural crops in the state.
