AI weather Artificial rain enhancement

Recently, the high temperature in Zhejiang has become a hot topic. In order to alleviate the adverse effects of persistent high temperature and drought, many places in Zhejiang Province have carried out large-scale artificial rainfall enhancement, which not only brings some coolness to the hot summer, but also helps alleviate the Meteorological drought and lowering forest fire danger levels have played a positive role. So, how is artificial rainfall enhancement carried out? What's the mystery behind it?

There are many black technologies for cooling down and relieving drought. What's the mystery behind artificial rainfall enhancement?

Affected by the continuous sunny, hot and high temperature weather, Zhejiang province has experienced a regional severe drought. Most areas in northern Zhejiang have experienced moderate to severe meteorological drought, with local extreme drought. On July 17, according to the analysis of cloud and water conditions, northern Zhejiang, western Zhejiang and coastal areas have certain conditions for rainfall enhancement operations. Therefore, the Zhejiang Provincial Meteorological Department seized the favorable weather situation and quickly carried out large-scale artificial rainfall enhancement operations.

Under the combined effect of natural rainfall and artificial rainfall enhancement, the precipitation effect in many places in Zhejiang Province is obvious. From 11:00 to 17:00 on July 17, the average rainfall in Zhejiang Province reached 2.6 mm, and rainfall occurred in 11 cities. Among them, Jiaxing has the highest average rainfall, reaching 12.9 mm. On July 18, there are plans for artificial rainfall enhancement operations in 40 places including Hangzhou, Ningbo Fenghua, Shaoxing Keqiao, Huzhou, and Jinhua Lanxi.

Artificial rainfall ≠artificial rainfall

Many people simply understand artificial rainfall as "artificial rainfall". Although they are both artificial weather modification operations, there are actually essential differences between the two. Artificial rain enhancement is not about creating rain out of thin air, but when encountering clouds with their own precipitation conditions, using scientific and technological means to "stimulate" them, thereby achieving the effect of increasing rainfall and extending rainfall duration.

What conditions need to be met to carry out artificial rainfall enhancement?

Some netizens said: "Thanks to artificial rainfall enhancement, 'Zhegong' has returned to Zhejiang." Many netizens also wondered why artificial rainfall enhancement was not carried out earlier, so as to alleviate the high temperature as soon as possible. Condition. This is because artificial rain enhancement is a "system" project and is not arbitrary. It needs to meet the following prerequisites:

Meteorological Department: Artificial rainfall enhancement cannot be done out of thin air by the meteorological department. , continuous sunny and hot temperatures, agricultural drought, environmental pollution, and high levels of forest fire danger are required.

Natural conditions: The rainfall increase rate of artificial weather modification is about 10% to 20%. However, artificial rain enhancement operations require suitable weather conditions to be carried out. There are no conditions for artificial rainfall enhancement operations on sunny days or with few clouds.

Ground conditions: Artificial rainfall enhancement can only be carried out under the premise of ensuring absolute safety, especially rocket rainfall enhancement operations. The height that rockets can reach is basically 4000 meters to 8000 meters. Close cooperation from airspace management departments is required. City centers with high population density do not have the conditions for artificial rainfall enhancement.

Therefore, whether it is artificial rainfall enhancement operations or other artificial weather modification operations, coordination and operation plans will generally be made at least three days in advance.

The "black technology" behind artificial rain enhancement

There are four main ways to artificially increase rainfall: ground rockets, smoke furnaces, gas cannons and aerial aircraft. Among them, rocket operations and ground smoke furnace operations are currently the most commonly used methods of artificial rainfall enhancement. So what other “black technologies” are behind artificial rainfall enhancement?

Compared with the traditional silhouette operation process, today's rocket launchers are also connected to the Internet. The Internet of Things can strengthen the safety management of key links such as operation equipment and ammunition, and can promptly discover, promptly remind, and promptly handle existing problems. After workers download the terminal, they can monitor it on their mobile phones, which is very convenient.

The new generation rocket launcher safety locking device also improves the safety of the operation by optimizing the digital password structure and verification process. Through the two-in-one identification link of password and fingerprint and the multi-person identity confirmation link, it can ensure In the event that a single password is leaked, the safe locked state of the operating equipment can still be ensured.

Safety is the lifeline of artificial rainfall enhancement operations. Whether it is rainfall enhancement by aircraft or rockets, the meteorological department also needs to cooperate with military and civil aviation, airports and other departments to strictly abide by airspace management and other related systems.

Conclusion: Generally speaking, it is a good thing to use modern science and technology to artificially increase rainfall in the face of high temperatures. Its quantity, scope, and conditions are strictly controlled by meteorological staff, and rain-increasing bombs are launched on a reasonable basis with "every benefit and no harm." However, artificial weather modification cannot change the inherent laws of the weather system and subsequent weather trends. According to the forecast of the meteorological department, after a brief relief from the high temperature, the hot weather will "return" around July 20. ​

Improve developer productivity, efficiency, and accuracy by incorporating retrieval-enhanced generation and semantic memory into AI coding assistants. Translated from EnhancingAICodingAssistantswithContextUsingRAGandSEM-RAG, author JanakiramMSV. While basic AI programming assistants are naturally helpful, they often fail to provide the most relevant and correct code suggestions because they rely on a general understanding of the software language and the most common patterns of writing software. The code generated by these coding assistants is suitable for solving the problems they are responsible for solving, but often does not conform to the coding standards, conventions and styles of the individual teams. This often results in suggestions that need to be modified or refined in order for the code to be accepted into the application

These questions It requires thinking outside the box. Large Language Models (LLMs) are increasingly important in the fields of data science, generative artificial intelligence (GenAI), and artificial intelligence. These complex algorithms enhance human skills and drive efficiency and innovation in many industries, becoming the key for companies to remain competitive. LLM has a wide range of applications. It can be used in fields such as natural language processing, text generation, speech recognition and recommendation systems. By learning from large amounts of data, LLM is able to generate text

Can fine-tuning really allow LLM to learn new things: introducing new knowledge may make the model produce more hallucinations Can fine-tuning really allow LLM to learn new things: introducing new knowledge may make the model produce more hallucinations Jun 11, 2024 pm 03:57 PM

Large Language Models (LLMs) are trained on huge text databases, where they acquire large amounts of real-world knowledge. This knowledge is embedded into their parameters and can then be used when needed. The knowledge of these models is "reified" at the end of training. At the end of pre-training, the model actually stops learning. Align or fine-tune the model to learn how to leverage this knowledge and respond more naturally to user questions. But sometimes model knowledge is not enough, and although the model can access external content through RAG, it is considered beneficial to adapt the model to new domains through fine-tuning. This fine-tuning is performed using input from human annotators or other LLM creations, where the model encounters additional real-world knowledge and integrates it

Editor |ScienceAI Question Answering (QA) data set plays a vital role in promoting natural language processing (NLP) research. High-quality QA data sets can not only be used to fine-tune models, but also effectively evaluate the capabilities of large language models (LLM), especially the ability to understand and reason about scientific knowledge. Although there are currently many scientific QA data sets covering medicine, chemistry, biology and other fields, these data sets still have some shortcomings. First, the data form is relatively simple, most of which are multiple-choice questions. They are easy to evaluate, but limit the model's answer selection range and cannot fully test the model's ability to answer scientific questions. In contrast, open-ended Q&A

SOTA performance, Xiamen multi-modal protein-ligand affinity prediction AI method, combines molecular surface information for the first time SOTA performance, Xiamen multi-modal protein-ligand affinity prediction AI method, combines molecular surface information for the first time Jul 17, 2024 pm 06:37 PM

Editor | KX In the field of drug research and development, accurately and effectively predicting the binding affinity of proteins and ligands is crucial for drug screening and optimization. However, current studies do not take into account the important role of molecular surface information in protein-ligand interactions. Based on this, researchers from Xiamen University proposed a novel multi-modal feature extraction (MFE) framework, which for the first time combines information on protein surface, 3D structure and sequence, and uses a cross-attention mechanism to compare different modalities. feature alignment. Experimental results demonstrate that this method achieves state-of-the-art performance in predicting protein-ligand binding affinities. Furthermore, ablation studies demonstrate the effectiveness and necessity of protein surface information and multimodal feature alignment within this framework. Related research begins with "S

Five schools of machine learning you don't know about Five schools of machine learning you don't know about Jun 05, 2024 pm 08:51 PM

Machine learning is an important branch of artificial intelligence that gives computers the ability to learn from data and improve their capabilities without being explicitly programmed. Machine learning has a wide range of applications in various fields, from image recognition and natural language processing to recommendation systems and fraud detection, and it is changing the way we live. There are many different methods and theories in the field of machine learning, among which the five most influential methods are called the "Five Schools of Machine Learning". The five major schools are the symbolic school, the connectionist school, the evolutionary school, the Bayesian school and the analogy school. 1. Symbolism, also known as symbolism, emphasizes the use of symbols for logical reasoning and expression of knowledge. This school of thought believes that learning is a process of reverse deduction, through existing
