الخلاصة: متوسط موعد آخر صقيع احتمال بنسبة 50%، وليس وعدًا —
نصف السنوات يأتي فيها الصقيع بعده. ازرع المحاصيل الحسّاسة على موعد الـ 10% إن كان البدء من جديد سيؤلمك.
كيف بُنيت هذه الأرقام
بالنسبة إلى المواقع الـ116 التي لها محطة، تواريخ الصقيع معدلات محطات مرصودة من U.S. Climate Normals للفترة 1991–2020 الصادرة عن NOAA (العنصران
ANN-TMIN-PRBLST-T32FP50 و-PRBFST-، عند مستويَي احتمال 50% و10%).
أما المواقع الـ425 الأخرى فمقدَّرة من شبكة مناخية بدقة نصف درجة مستوفاة من المعدلات نفسها، وتذكر كل صفحة منها ذلك.
مناطق التحمّل الشتوي من خريطة USDA Plant Hardiness Zone Map لعام 2023. ومواعيد المحاصيل محفوظة كفروق بالأيام عن
تواريخ الصقيع عندك، مأخوذة من أدلة الزراعة في برامج Extension الجامعية؛ أما مواعيد الخريف فتستخدم طريقة العدّ العكسي
المعتادة في Extension، بما فيها «معامل الخريف» لقصر النهار.
لا تجد بلدتك؟ تطبيق Moon Phase Garden يحدّد موقعك بدقة على شبكة المعدلات المناخية كاملةً بدل أقرب محطة كبيرة، ويتيح لك تعديل الأرقام بما تفعله حديقتك فعلًا. مجاني وبلا إعلانات.
