📌 Dust Storm Analysis over Uzbekistan (May–June 2023)

🌪 A comprehensive dust storm analysis was carried out using Aerosol Optical Depth (AOD), 🌡 Land Surface Temperature (LST), and 🌧 Rainfall indicators. The analysis covers May–June 2023 and was conducted entirely through Google Earth Engine (GEE).

🛰 The project leverages MODIS and CHIRPS satellite datasets for large-scale, cloud-based geospatial processing.

🔍 Key Findings:

🔴 AOD > 0.3 indicates areas highly affected by aerosols, i.e., potential dust storm zones (visualized in red and purple).

🔥 Regions with elevated land surface temperature suggest dry and heat-prone conditions.

☔️ Rainfall distribution adds additional insight into local climate impacts during the dust events.

📍 Study Region: Uzbekistan

📌 O‘zbekistonda chang bo‘ronlarini tahlil qilish (2023-yil May–Iyun)

🌪 2023-yilning may–iyun oylarida O‘zbekiston hududida yuz bergan chang bo‘ronlari holati Aerosol Optical Depth (AOD), 🌡 Yer yuzasi harorati (LST) va 🌧 yog‘ingarchilik ko‘rsatkichlari asosida tahlil qilindi. Ushbu tahlil to‘liq Google Earth Engine (GEE) platformasi orqali amalga oshirildi.

🛰 Loyihada MODIS va CHIRPS sun’iy yo‘ldosh ma’lumotlari asosida katta hududlarni bulutli hisoblash imkoniyati bilan geotahlil qilindi.

🔍 Asosiy natijalar:

🔴 AOD > 0.3 bo‘lgan joylar aerozollar bilan kuchli ifloslangan bo‘lib, bu chang bo‘roni xavfini bildiradi (qizil va binafsha ranglar bilan ifodalangan).

🔥 Yuqori yer harorati kuzatilgan hududlar qurg‘oqchil va issiqlikka moyil ekani ko‘rsatildi.

☔️ Yog‘ingarchilik tarqalishi esa chang hodisalarining mahalliy iqlimga ta’sirini chuqurroq tushunishga yordam beradi.

📍 Tadqiqot hududi: O‘zbekiston

🌊 Orol dengizi – Qayta tiklanishi mumkinmi?

🔴

To‘liq avvalgi holatga qaytarish – deyarli imkonsiz
Orol dengizi XX asrda dunyodagi to‘rtinchi yirik ichki dengiz bo‘lgan (68 ming km²), lekin hozirgi (2024) holatiga ko‘ra 90% dan ortiq qismini yo‘qotgan.

Sabablar:

Amudaryo va Sirdaryo suvining massiv sug‘orish uchun yo‘naltirilishi

Suv tejash texnologiyalarining yo‘qligi

Har yili ortib borayotgan bug‘lanish

Iqlim o‘zgarishi va kam yog‘ingarchilik

✅ Qisman tiklash – ha, mumkin
Shimoliy Orol dengiz (Qozog‘iston qismi) – qisman tiklangan yagona hudud:

Kokaral to‘g‘oni (2005 yilda qurilgan) orqali shimoliy qismda suv sathi oshdi.

Baliqchilik qayta rivojlandi, havoning sifatiga ijobiy ta’sir ko‘rsatdi.

📌 Loyiha misoli:

👉 “Aral Sea Restoration Project” – World Bank, Qozog‘iston hukumati bilan hamkorlikda olib borilgan.

🧪 Qanday chora-tadbirlar orqali qisman tiklash mumkin?
Amudaryo va Sirdaryo havzalarida suvni tejash texnologiyalarini joriy qilish

Suv tejovchi sug‘orish tizimlari (drip irrigation) kengaytirish

Ekologik zonalash va tuproq sho‘rlanishini kamaytirish

Yashil zonalarni ko‘paytirish (“Green Belt” loyihalari)

Xalqaro yordam va regional hamkorlik (Uzbekistan-Qozog‘iston-Turkmaniston)

⚠️ Nega bu muhim?

Ekologik halokat: sho‘rlangan maydonlar, chang bo‘ronlari, sog‘liq muammolari

Ijtimoiy falokat: migratsiya, baliqchilik yo‘qolishi, daromad manbalarining tugashi

Iqlimga ta’siri: lokal issiqlik, namlik kamayishi
